What is the temperature rating of the lugs for QB, QD , QG , QJ breakers ?

Issue:
What is the temperature rating of the lugs for  QB, QD , QG , QJ  breakers ?

Product Line:
Powerpact QB, QD , QG , QJ 

Resolution:
The terminal is rated 75 deg C.  
Underwriter Laboratories Inc. (UL) standards require that molded-case circuit breakers rated at 125 amperes or less be marked with the conductor insulation-temperature rating. Circuit breakers rated above 125 deg. C are required to be suitable for 75 deg. C wire and need not be so marked.
Note that conductors with 90°C rated insulation can be used on circuit breakers rated for 60°C or 75°C wiring, but only if their size is based on the ampacity of the lower temperature-rated wire.
