HFB and MCP Molded Case Circuit Breakers

HFB and MCP molded case circuit breakers are used in motor control centers and a vast majority of circuit protection applications. The current manufacturer of these specific breakers has announced it will discontinue the product line and no longer accept orders after December 31, 2017. Westinghouse will continue to support all HFB and MCP replacement breakers.

Alternative replacements are available for all discontinued circuit breakers, except the 10 Amp HFB1010, HFB2010 and HFB3010. Since these components cannot be repaired and only have a qualified lifespan of 20 years, we urgently recommend acquiring any breakers in this category in sufficient quantity to allow for reliable plant operation and to avoid design changes in the future. In the spirit of Delivering the Nuclear Promise, Westinghouse is offering a discount on all HFB and MCP molded case circuit breakers until the manufacturer’s cutoff date.

Please contact your Westinghouse nuclear parts specialist to place your order as soon as possible!
