SCJD69400G - 400Amp Circuit Breaker

SCJD69400G - 400Amp Circuit Breaker

The Siemens SCJD69400G is a 400-amp, 3-pole molded-case circuit breaker (MCCB) for your compatible commercial and industrial electrical distribution systems. Part of the Siemens SENTRON family, this breaker features an SJD configuration, JD frame, and SensiTrip electronic trip unit (ETU) with long-time, instantaneous, and ground-fault (LIG) protection functions. Rated for electrical systems up to 600V AC, the SCJD69400G has an interrupting capacity of 100kA at 600V AC and 150kA at 480V AC.

Key Features and Benefits
