Customer requests the ability to change sensor plugs on the Powerpact breakers (P and R frames), like we do on NT and NW.

Product Line:
Circuit Breakers

Environment:
Powerpact P and R, Masterpact NW and NT
Trip Units this applies to: Standard, Ammeter, Power, and Harmonic

Resolution:
Sensor Plugs can be replaced only on circuit breakers with date codes later than 07011.

NOTE: This does not apply to ET 1.01 Trip units, sensor is fixed and cannot be changed. 

Installation Notes:
Masterpact NT and NW:  sensor plugs are field installable down to 50% of the FRAME  rating.   Example:  A Masterpact with a 1600 amp frame can receive sensor plugs from 800-1600 amps.
 
Powerpact P and R:  sensor plugs are field installable down to 50% of the CURRENT rating.  Example:  A Powerpact P frame breaker with 800 amp sensor installed at the factory can only receive sensors from 400-800 amps.  You can't go higher than what was originally installed at the factory.
