Most of today’s circuit breakersdesigned for simple protection functions in final distribution applications are non-adjustable, so they do not require any unique configuration. However, circuit breakers designed for LV applications above 100A in main switchboards – i.e., molded case circuit breakers (MCCB) and air circuit breakers (ACB) – typically...
There are three important reasons to check circuit breakers to certify proper configuration and operation: 1. Safety– The ability of a circuit breaker to reliably disconnect in the case of overcurrent or earth fault is a matter of property and people protection. Proper functioning relies on consistency between circuit-breaker setting, tripping curv...
As per the standards noted above, checking LV circuit breaker settings should be executed multiple times over the circuit breaker’s lifecycle. Here are some additional considerations:
