   • The Importance of Properly Configuring Lv Circuit Breakers
   • Circuit Breaker Checking Validates The Configuration
   • Recommended Steps For Circuit Breaker Testing
   • New Technology Makes Circuit Breaker Testing Simpler, Faster, and More Reliable

   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...
