Description:
The Westinghouse GFN425N BU molded case circuit breaker is a 400 A, 240 V, 3-phase unit in the GFN series designed for industrial electrical distribution and branch-circuit protection. This 3-pole, thermal-magnetic breaker provides overcurrent and short-circuit protection for high-amperage three-phase equipment in switchboards, panelboards, MCCs, and industrial automation systems operating on 50/60 Hz. The NN1 designation indicates an inventory/condition notch associated with the part, and it is commonly panel- or switchboard-mounted for easy integration into power distribution arrangements. Common replacements include Eaton GFN425N, Siemens JXD63B400, and Square D LA36400.
