SJD69400NGT - 400Amp Circuit Breaker Description
SJD69400NGT - 400Amp Circuit Breaker
When your electrical distribution system calls for dependable overcurrent protection, the SJD69400NGT molded case circuit breaker delivers the ratings and adjustability needed for a wide range of commercial and industrial applications. Built on a 400-amp SJD frame, this 3-pole thermal magnetic circuit breaker is designed as a form, fit, and functional replacement for compatible equipment, making it an excellent choice for maintaining existing electrical systems without changing the original design.
One feature that sets the SJD69400NGT apart is its adjustable electronic trip functions, giving qualified personnel the flexibility to tailor protection settings to the needs of the electrical system. Adjustable settings include continuous current, long-time delay, instantaneous protection, short-time pickup and delay, short-time I²t pickup, ground fault pickup, and ground fault delay, allowing for more precise coordination with other protective devices. Built to last, this breaker helps protect electrical equipment from overloads and short circuits while supporting reliable system operation.
