EHB3050 - 50Amp Circuit Breaker

EHB3050 - 50Amp Circuit Breaker

Selecting the correct replacement circuit breaker means matching the original equipment specifications, not just the amperage. The EHB3050 is a 3-pole, 50-amp Type EHB thermal-magnetic circuit breaker designed to provide the form, fit, and functional compatibility required for electrical systems using compatible pre-1989 panelboards. Whether you're maintaining an existing commercial facility, industrial plant, or institutional building, this breaker is intended to help keep legacy electrical distribution systems operating as originally designed. Its non-interchangeable thermal-magnetic trip unit provides protection against both overloads and short circuits while maintaining the original breaker configuration.
