Difference between MCB, MCCB, RCCB, RCBO and Isolator


Circuit breakers are safety devices, which ensures the safety of equipment and personnel from electric shocks and damages. They are self-acting and should safely interrupt the current flow on the event of faults. Circuit breakers are a cost-effective and efficient alternative to traditional circuit protection fuses. These devices are reusable and may help in saving a lot of money and downtime. (more…)

Isolator/ Disconnectors

Isolator or disconnectors, as the name indicates, is a switching or isolation device, intended to disconnect an equipment or electrical Circuit from the supply. It is an offload device, which means it can be operated only when the current passing through it is zero. Unlike circuit breakers, it lacks a built-in arc suppression system. It can be operated only during offload conditions. (more…)
