Circuit breaker, PowerPacT L, 400A, 3 pole, 600VAC, 25kA, I-Line, Micrologic 6.3A, 100%, ABC

PowerPact L circuit breakers provide versatile, 3 and 4 pole designed breakers for applications such as construction, commercial buildings, and industrial buildings and applications. All PowerPact circuit breakers have an integral push-to-trip button that allows manual trip and have a trip-free mechanism to allow tripping even if the operating handle is restricted. Accessories and auxiliaries across the range allow users to reduce inventories without sacrificing flexibility. These breakers have multiple connection and termination options available. This I-Line mount three pole breaker is rated for 400A and 600VAC with a 25kA interrupting rating at 600VAC. It is 100% rated, UL certified current limiting circuit breaker. It has a MicroLogic Ammeter electronic trip unit, with LSIG function and 6.3A trip unit. It comes with lugs on the load side and I-Line connection on the line side for electrical connection. These circuit breakers are UL, CSA, and NOM certified.
