What is the terminal temperature rating on Powerpact M, P, and R frame circuit breakers?
What is the terminal temperature rating on Powerpact MG, MJ, PG, PJ, PK, PL, RG, RJ, RK, and RL circuit breakers?
Powerpact M, P, R circuit breakers
The termination rating for these circuit breakers is 75 deg. C. This means that if terminated with cable, the insulation rating must be 75 deg. C or greater, and the conductor size must be based on its 75 deg. C ampacity.
Circuit breakers rated above 125 deg. C are required to be suitable for 75 deg. C wire and need not be so marked.
