PROTEUS Technical Information Switchgear Derating Adjacent MCBs, RCBOs or MCB/RCD combinations should not be continuously loaded at, or approaching, their normal rated currents when mounted in enclosures. It is also good engineering practice to make provisions for adequate free air between devices. Under these circumstances and, in common with other manufacturers, we recommend a diversity factor of 66% is applied to the MCB nominal rated current, especially if the MCB is expected to be loaded near to or at full rating for more than one hour. Thermal issues should also be taken into consideration when choosing conductor size for the protected circuits. Generally the MCBs detailed are not intended to provide close overload protection for motors. However they can be employed in conjunction with the customary motor overload current device as an alternative to the isolator/fuse combination. In this condition the MCB will protect the cable to the motor and the motor will be protected by its own protective device. The tables A and B detailed below give recommendations on MCB selection for motor circuits, for C type only. Note: The values of full load current and starting current will approximately be 10% higher at 380/220V ac than the figures stated for 400/230V motors. The figures given in table A for the starting current and its duration are intended to be used as a guide only. In practice the motor run up time will depend upon the type of drive and the loading of the motor when it is started. Consultation with the motor manufacturer should give an indication of the magnitude of the starting current and the duration. The selection of the most suitable circuit breaker can then be found from the time/current characteristics of the circuit breaker.

RCBOs are available in a range of current ratings from 6A to 50A and with short circuit capacities (Ics) from 4.5kA up to 10kA. RCBOs are offered in both type B and C tripping characteristics. All single module RCBOs contain a switched live and solid neutral where as the double module unit offers both Live and Neutral switching. Similar to our MCB technology all devices have a ‘trip free Standards: Operating voltage: Earth leakage sensitivity: Switching: Operating frequency: Ambient operating temp.: Maxi. terminal torque: Enclosure material: Supply connections: IP rating: Dielectric voltage: Insulation voltage: 90 RCBOs mechanism’ and positive contact status indication. Connection of load circuit cables is via tunnel design cable clamps with touch proof and captive terminal screws. Lockable in both ON and OFF position without affecting the ability of the trip mechanism to operate. RCBOs allow earth fault protection to be restricted to individual circuits, thus ensuring that only the circuit with the fault is interrupted. (When groups of circuits are protected by an RCD, all circuits would be interrupted under a fault condition, which may cause unnecessary inconvenience).

Proteus RCDs are available in a wide range of earth leakage sensitivities and current ratings to meet the majority of applications. Residual Current Devices (RCDs) come in both 2 pole and 4 pole options. Proteus RCDs incorporate the latest in electronic earth leakage detection technology ensuring consistent reliable performance. With sufficient contact gap, switching of all Live and Neutral conductors and positive contact indication in accordance with the IEE wiring regulation these devices can be used for isolation purposes. RCDs also incorporate ‘trip free mechanism’ technology and can be locked ON or OFF with suitable locking device (eg. DLPX1) without affecting the devices ability to offer protection under fault conditions. PROTEUS Technical Information RCDs General use RCDs for domestic single phase or light commercial three phase systems are required to be either Type AC or Type A. This type reference defines the nature of the earth leakage which the RCD is expected to detect and protect against. Type AC: Tripping is ensured for residual sinusoidal alternating currents, whether suddenly applied or slowly rising. Identified by the symbol: Type A: Tripping is ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowly rising.

Surge Protection Devices to fit a fuse or circuit breaker the ‘IF’ (Internal Fuse) version is available. Their protection is limited by distance with a general protection zone of <10m. Equipment further away necessitate the installation of an additional Type 2 units in sub-distribution boards. These Type 1 SPDs must be installed on incoming services (e.g. mains power and data) when an external Lightning Protection System (LPS) is installed on a building. Where partial lightning currents can also flow due to a direct lightning strike on overhead supplies or externally mounted equipment, Type 1 SPDs should also be used. Combined Type `1 + Type 2 SPDs are installed at the origin of the supply to the building, normally within the main switchboard. If the installation being protected is already fitted with an SCPD of 315A or less then the SPD can be connected direct to the busbar otherwise ensure the device is adequately protected. In installations where it is not possible to fit a fuse or circuit breaker the ‘IF’ (Internal Fuse) version is available. Type 2 and Type 3 SPDs are designed to discharge the induced surges created by lightning electromagnetic fields and also other transient surge events such as switching surges, supply faults etc. These devices are defined as being tested with a specific energy wave shape of 8/20μs (In) for Type 2 SPDs or a combination wave shapes for Type 3 SPDs. For many applications where the requirement is to provide surge protection only, Type 2 and Type 3 SPDs play a critical role in protecting electronic equipment. Type 2 SPDs in this modular form offer more general surge protection for equipment within the installation from sources of problematic electrical surges internal to the building (typically switching transients). If the installation being protected is already fitted with an SCPD of 125A or less then the SPD can be connected direct to the busbar otherwise ensure the device is adequately protected. In installations where it is not possible www.proteusswitchgear.co.uk Type 3 SPDs provide the primary ‘fine protection’ from surges, giving high sensitive equipment that added level of security. As a rule they should be installed as close as possible to the equipment being protected. This class of product is available in both din-rail mounting version or remote/local installation. For example the SPD/ T3/LPC can be wired into the back of a plug socket feeding a certain piece of equipment. The SPD/T3/LPC has also the benefit of an audible alarm, for when the unit requires replacing. Technical Information Type 1 SPDs are key to providing necessary protection of the installation against the effects of lightning strikes entering the building. Type 1 SPDs are designed to carry partial lightning currents and are defined as being tested with a high energy 10/350μs (Iimp) wave shape. 91

However, when used in tandem with any intrinsic motor overload device they provide an excellent alternative to the combined isolator and fuse arrangements. In this case the motor is protected by its own circuit breaker. In order to select the correct MCCB, consideration should be given to individual MCCB time/current characteristics (for full details please refer to works). This should only be undertaken in conjunction with information provided by the motor manufacturer as to starting current and duration. The motor protection table shown provides a guide to MCCB selection based on the start current and duration indicated and it must always be noted that the drive and motor loading will affect the motor run up time. (i) The figures shown are based on the assumption that the motor starting conditions are: Direct On-Line =7 x full load current for 5 seconds max. Moulded case circuit breakers are commonly applied to capacitor currents. However, due to high in-rush currents and harmonic content found in capacitor circuits, MCCBs should be rated > 1.5 times the current rating of the capacitor. It is recommended that the MCCB should be utilized as a main isolation/protection device to the capacitor bank. (i.e. occasional switching). Capacitors should be individually protected and switched by appropriately rated contactors. MCCB Protection of Capacitor Circuits Motor Rating (kW) Motor Rating (HP) Approx.

PROTEUS Technical Information Ingress Protection (IP Rating) IEC/EN 60529 is an international set of test specification standards for classifying the degrees of protection provided by the enclosures of electrical equipment against the intrusion into the equipment of foreign bodies (i.e. tools, dust, fingers, etc) and moisture. This classification system utilizes the letters “IP” (“Ingress Protection”) followed by two or three digits. (A third digit is sometimes used. An “x” is used for one of the digits if there is only one class of protection; i.e. IPX4 which addresses moisture resistance only.) The first digit of the IP code indicates the degree that persons are protected against contact with moving parts (other than smooth rotating shafts, etc.) and the degree that equipment is protected against solid foreign bodies intruding into an enclosure. The second digit indicates the degree of protection of the equipment inside the enclosure against the harmful entry of various forms of moisture (e.g. dripping, spraying, submersion, etc.) [For full details consult IEC/EN60529] 1st Digit Protection from solid objects 2nd Digit Protection from moisture 1 Protected against solid object greater than 50mm 1 Protection against vertically dripping water 2 Protected against solid object greater than 12.5mm 2 Protection against dripping water when tilted upto 15degrees 3 Protected against solid object greater than 2.5mm 3 Protection against spraying water 4 Protected against solid object greater than 1mm 4 Protection against splashing water 5 Dust protected 5 Protection against jetting water 6 Dust tight 6 Protection against powerfully jetting water 7 Protection against the temporary affects of immersion 8 Protection against continuous submersion Applicable Standards Though not exhaustive the below table lists the British / European harmonised standards to which products in this catalogue comply (where applicable).

When the load is connected to the supply through an RCD, the live and neutral conductors are connected through a primary winding on a toroidal transformer. In this arrangement the secondary winding is used as a sensing coil and is electrically connected to a relay or solid-state switching device, the activation of which triggers the mechanical tripping mechanism. When the live and neutral currents are balanced, as in healthy circuit they produce equal and opposite magnetic fluxes in www.proteusswitchgear.co.uk the transformer core with the result that there is no current generated in the sensing coil. When the live and neutral currents are not balanced they create an out-of-balance flux. This will induce a current in the secondary sensing winding which is used to operate the tripping mechanism of the RCD. Circuit Protection 100/4/30 35 63 53
