Product Line:
Powerpact P frame, Powerpact R frame, and Masterpact circuit breakers
Resolution:
The Ir or Long Time dial is set at 1.0.
All other trip unit adjustments (long time delay, short time pickup and delay, instantaneous, ground fault pickup and delay) are set fully counterclockwise at their lowest settings.
These settings are typically changed when the circuit breaker is installed. Settings for a specific application must be determined by a qualified consultant or plant engineer. A coordination study is recommended to provide coordination between all circuit breakers in the distribution system.
