EHB3070 - 70Amp Circuit Breaker

EHB3070 - 70Amp Circuit Breaker

If you're maintaining an existing electrical system that uses Type EHB circuit breakers, the EHB3070 is designed to provide the correct form, fit, and function for your application. This 3-pole, 70 amp thermal-magnetic circuit breaker is rated 14kA at 480VAC and was engineered for use in electrical panels manufactured before 1989. Its thermal-magnetic trip mechanism responds to both overloads and short circuits, helping protect connected equipment and electrical distribution systems during normal operation.

Whether you're replacing a worn breaker during scheduled maintenance or restoring an older panel to service, choosing the correct replacement is essential. The EHB3070 features a non-interchangeable trip unit, is rated at 40°C, and includes load terminals for added installation convenience.
