SHLD69400 - 400Amp Circuit Breaker

SHLD69400 - 400Amp Circuit Breaker

When you need a 400 amp molded case circuit breaker that matches the form, fit, and function of compatible electrical equipment, the SHLD69400 is designed to meet the job. Built on the SLD600A frame, this 3-pole thermal magnetic circuit breaker helps protect electrical distribution systems from overloads and short circuits while giving you the flexibility of an adjustable trip unit. The built-in adjustments for continuous current, long-time delay, and instantaneous trip settings allow the breaker to be configured to suit the protection requirements of many commercial and industrial applications. Designed to last, the SHLD69400 is commonly used in switchboards, panelboards, and other power distribution equipment where a Type SHLD6-A breaker is specified. With interrupting ratings of 35kA at 600VAC, 65kA at 480VAC, and 100kA at 240VAC, it is intended as a form, fit, and functional replacement for compatible existing installations.
