NJJ232250 - 250Amp Circuit Breaker Description
NJJ232250 - 250Amp Circuit Breaker
When you're replacing a circuit breaker in an existing electrical system, the details matter. You need more than the right amperage—you need the correct frame, mounting arrangement, pole configuration, and electrical ratings. The NJJ232250 250 Amp 2-Pole Bolt-On Circuit Breaker is a molded-case circuit breaker for electrical equipment that requires an NJJ-frame, 250 Amp, two-pole breaker with bolt-on mounting. For electricians and maintenance professionals working with compatible legacy electrical equipment, the NJJ232250 offers a practical way to maintain the original breaker's specified form, fit, and function.
The NJJ232250 also carries a 40°C temperature designation, which should be considered when evaluating the manufacturer's application requirements and the installation environment. Its molded case construction houses the switching and protective components in a single breaker assembly.
