The "P" in the code indicates it is equipped with a "PR332" series basic fixed protection trip unit. This is a non-adjustable, non-communicating electronic unit. Protection: It provides fundamental fixed Long-time (L) and Short-time (S) protection with factory-set thresholds based on the 4000A frame rating.
