Why do I need an over current release?
An overcurrent release provides a mechanical output when any of the current related values exceed their specified limits (overload, short circuit, ground fault, etc.). … This term is used in connection with tripping of circuit breaker on overload. Overload trip devices have inverse characteristics.
