MOLDED CASE CIRCUIT BREAKERS
CHARACTERISTIC TRIP CURVE NO. 961-1
Catalog Number Circuit Breaker CB Amps CB Voltage Number Of Poles
ELM150HD PowerPact H-Frame 15–150 600 3
ELM250JD PowerPact J-Frame 150–250 600 3
Total clearing times shown include the response times of the ELM,
the circuit breaker shunt trip, the circuit breaker opening, and the
extinction of the current. Curves apply from -30°C to +60°C ambient
temperature. Refer also to the circuit breaker trip curves for
PowerPact H- and J-Frame Circuit Breakers.
Note: Trip curves dene the performance under normal conditions.
Add 0.030 seconds for closing breaker/module on an existing fault.
