Earth Leakage Circuit Breaker ABB Nigeria
RCDs assure a protection to people and installations against fault current to earth. They are divided into three families. RCCBs, which are sensiti- ve only to earth fault current (therefore they have to be connected in series with a MCB or a fuse to protect them against overcurrents and short-circuits)
RCD-blocks, which are devices to be assembled on a MCB with lower or equal rated current to pro-vide protection against both earth-fault currents and overload or short-circuits. RCBOs, which combines in a single device protection against both earth-fault currents and overloads or short-circuits.
New RCDs System pro M compact range presents a wide offer for all the three families, respectively F 200, DDA 200 and DS 200 series. A large offer for standard instantaneous and selective AC and A types is completed with some configurations for special applications, like AP-R type against perturbations or AE type for emergency stop.

All sizes up to 63 A with all the sensitivity thresholds up to 1 A are offered in all the possible pole configurations. ABB RCDs obtained a lot of marks and approvals and offer the same “plus” advan- tages of the other System pro M compact devices.
What is an Earth Leakage Circuit Breaker (ELCB)?
An ECLB is one sort of well being Earth Leakage Circuit Breaker ABB Nigeria utilized for introducing an electrical gadget with high earth impedance to stay away from stun. These gadgets recognize little wanderer voltages of the electrical gadget on the metal fenced in areas and interrupt the circuit if a perilous voltage is distinguished. The principle reason for Earth spillage electrical switch (ECLB) is to stop harm to people and creatures because of electric stun.
An Earth Leakage Circuit Breaker ABB Nigeria is a particular sort of locking transfer that has a structure’s approaching mains power related through its exchanging contacts so the electrical switch withdraws the force in a hazardous condition.The ELCB sees shortcoming flows of human or creature to the earth wire in the association it monitors. In the event that plentiful voltage appears over the ELCB’s sense curl, it will kill the force, and stay off until physically revamp. A voltage detecting ELCB doesn’t recognize flaw flows from human or creature to the earth.
Working Principle Of Earth Leakage Circuit Breaker(ELCB) And Its Advantage and Disadvantages
Early earth spillage circuit breakers or Earth Leakage Circuit Breaker ABB Nigeria, are voltage distinguishing gadgets, which are presently exchanged by current detecting gadgets (RCD/RCCB). For the most part, the current detecting gadgets named as RCCB and voltage identifying gadgets named as Earth Leakage Circuit Breaker (ELCB). Forty years prior, the primary current ECLBs were presented and around sixty years back the main voltage ECLB was presented.
For quite a while, both the voltage and current worked ELCBs were both alluded to as ELCBs because of its straightforward name to recollect. Be that as it may, the uses of these two gadgets offered development to the huge misunderstanding in the electrical industry.
