SLD69400 - 400Amp Circuit Breaker Description

SLD69400 - 400Amp Circuit Breaker

The SLD69400 is a 3-pole, 400-amp thermal-magnetic molded-case circuit breaker built on the SLD600A frame for use in your commercial and industrial electrical distribution systems. Designed as a form, fit, and function replacement, this breaker provides dependable overcurrent and short-circuit protection for equipment operating on systems up to 600 VAC. Its adjustable trip unit allows users to fine-tune protection settings with Continuous Current Setting, Long Time Delay, and Instantaneous Setting functions, making it well-suited for applications where coordination with downstream devices is important. Built to last, the SLD69400 is intended for installations requiring a 400A breaker with the electrical ratings and physical compatibility of the SLD6-A family. Please note that lug terminals are not included and must be obtained separately if required for your installation.
