SND69120AG - 1200Amp Circuit Breaker

SND69120AG - 1200Amp Circuit Breaker

The SND69120AG circuit breaker is a 1200A, three-pole molded case breaker with an electronic LIG trip unit, designed for the ND-frame configuration used in your existing electrical distribution equipment. Rated for 600V operation, the breaker has an interrupting rating of 25kAIC at 600V and 50kAIC at 480V. For maintenance teams working with legacy equipment, the key is straightforward: match the catalog number, frame, amperage, voltage, interrupting capacity, trip functions, conductor requirements, and physical dimensions to the existing system. These circuit breakers are built to last, but correct application depends first and foremost on exact electrical and mechanical compatibility.

Key Features and Benefits

Where It Works Best

The SND69120AG 1200A circuit breaker is appropriate for existing and legacy electrical distribution equipment that specifically requires its ND-frame, three-pole, 1200A, 600V configuration and matching electronic LIG trip functions. It is especially relevant when maintaining equipment where preserving the established breaker configuration, electrical ratings, conductor connections, and physical footprint is necessary.
