What is the function of the alarm SD switch for the Powerpact R-Frame and P-Frame breakers?
ALARM SWITCH (SD)
The alarm switch indicates that the circuit breaker has tripped due to an overload, short circuit, operation of a voltage release, operation of the push-to-trip button or disconnection when the device is on. The alarm switch returns to the de-energized state when the circuit breaker is reset. The alarm switch is also available in a low-level version capable of switching very low loads.
