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.

For complete details on installing sensor plugs and their restrictions, please see attached instruction bulletin  48049-145-03.
