What is the 24 Vdc external power supply used for on Powerpact H,J,P,R frame breakers? How can the Display show status , if there is no load going thru the breaker?
Powerpaxt H,J,P,R breakers
For constant display indication of the breaker's status with less than 20% loading , a Power supply is sometimes desired.

2) Maintain display of tripping causes after opening of the circuit breaker.
3) Store the value of the interrupted current (P and H trip units only).
