Most of today’s circuit breakers designed 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 100 A in main switchboards  typically integrate protection for many fault conditions, like overload, short circuit, and earth fault. Many of these breakers configure to coordinate protection between each other – using selectivity and cascading – to help minimise impacts of electrical faults while preserving supply continuity for the rest of a facility. Circuit breakers offering this level of protection and reliability have adjustable settings that need configuration.
