The Siemens HJD63B250 is a 250-amp, 3-pole, 600V high-AIC J-Frame molded case circuit breaker from the Sentron Series HJD line. It delivers a 65kAIC interrupting rating at 480V and 100kAIC at 240V, making it ideal for high-fault-current industrial and commercial applications. The HJD frame covers 200 to 400 amps with an interchangeable trip unit and ships assembled with aluminum/copper lugs. The HJD63B250 is compatible with Siemens NEMA-type switchboards and is a direct replacement for legacy ITE HJD units.
