EHB2040 - 40Amp Circuit Breaker

EHB2040 - 40Amp Circuit Breaker

The EHB2040 is a 2-pole, 40 Amp Type EHB thermal-magnetic circuit breaker designed as a form, fit, and function replacement for compatible electrical distribution systems that use Type EHB breakers. Specifically engineered for installation in electrical panels manufactured before 1989, this breaker helps provide dependable protection against overloads and short circuits through its thermal-magnetic operating mechanism.

Whether you're replacing an existing breaker during routine maintenance or restoring service in a legacy electrical system, the EHB2040 provides the ratings and compatibility needed for matching Type EHB applications. Its design helps maintain the integrity of the original panel configuration without requiring modifications, making it a practical solution for facilities that continue to rely on proven electrical infrastructure.
