ELECTRICAL HISTORY

Ultimate protection of people and equipment The Residual Current Circuit breaker RCCBs are the safest device to detect and trip against electrical leakage currents, thus ensuring protection against electric shock caused by indirect contacts. These devices must be used in series with an MCB or fuse which protects them from the potentially damaging thermal and dynamic stresses of any overcurrents. They also act as the main disconnecting switches upstream of any derived MCBs (e.g. domestic consumer unit).  Main benefits       Safety performances ensured worldwide by international marks approval High-quality execution and attention to details Complete range of products and related accessories Main Features   AC, A, B, APR types available to ensure protection against all kinds of earth fault currents Rated Currents from 16A up to 125A Rated I∆n Sensitivity 10, 30mA, 100mA, 300mA, 500mA and 1A

POST BY                GUDDU YADAV Electrical circuit breaker is a one kind of switching device which can be activated automatically as well as manually to control and protect an electrical power system respectively. As the current power system deals with vast currents, the special notice should be given throughout designing of circuit breaker to secure break of arc produced during the process of the circuit breaker. This was the fundamental definition of circuit breakers. These have been divided into a various types based on special categories they have been subdivided into. Difference Between MCB and MCCB, ELCB, RCCB The different circuit breakers and difference between MCB and MCCB, ELCB and RCCB are discussed below. MCB-Miniature Circuit Breaker MCB is an electromechanical device which guards an electrical circuit from an over current, that may effect from short circuit, overload or imperfect design. This is a better option to a Fu...
