Difference between circuit breaker and isolator

The circuit breakers and isolators serve a common purpose of circuit interruption. The primary difference between them lies in their behavior during faults in the circuit. In this article, let’s discuss the difference between a circuit breaker and an isolator. Isolator/ Disconnectors An isolator or disconnector, as the name indicates, is a switching or isolation … Read more

Difference between MCCB and RCCB

Difference between MCCB and RCCB MCCBs and RCCBs are circuit protection devices with two different application. When the former protect against overload and short circuit, the later protects against Residual currents and electric shock. MCCB- Molded Case Circuit Breakers Moulded Case Circuit Breakers protect against overcurrent and short-circuits only unless otherwise, they have inbuilt residual protection. MCCBs trip as … Read more
