ISSUE
What is the function and electrical characteristics of the auxiliary switch, alarm switch and overcurrent trip switch for the PowerPact P, R, and NS630b - NS3200 electronic trip circuit breakers?

PRODUCT LINE
PowerPact and Masterpact breakers

ENVIRONMENT
It applies to any PowerPact or Masterpact breaker including an OF Auxiliary switch, SD Alarm switch or SDE Overcurrent trip switch.

CAUSE
Need to know the function of each of the different switches.

RESOLUTION
AUXILIARY SWITCH (OF)
An auxiliary switch is a single-pole, double-throw switch operated by the movable contact arm assembly.
It is used to remotely indicate the position of the main circuit breaker contacts, whether open or closed.
Auxiliary switches can be used to operate indicator lights, relays or other accessories.
ALARM SWITCH (SD)
An alarm switch indicates that the circuit breaker has tripped due to an overload, short circuit or ground fault, the operation of a shunt trip or undervoltage trip or the "push-to-trip" button.
The alarm switch resets when the circuit breaker is reset.
OVERCURRENT TRIP SWTCH (SDE)
An overcurrent trip switch indicates that the circuit breaker has tripped due to an overload, short circuit or ground fault.
The overcurrent trip switch resets when the circuit breaker is reset.
These switches are available in low-level versions (with gold flash plating) capable of switching very low loads (e.g., for controlling PLC's or electronic circuits).
