EHB1030 - 30Amp Circuit Breaker Description
EHB1030 - 30 Amp Circuit Breaker
If you’re maintaining an older panel and need a breaker that actually fits without guesswork, the EHB1030 is exactly what you’re looking for. This 30-amp, single-pole circuit breaker was built for use in panelboards manufactured before 1989, making it a reliable match for legacy systems that still need to perform day in and day out. It uses a thermal-magnetic trip mechanism to handle both overloads and short circuits, giving you the kind of protection these systems were originally designed around. With its fixed trip unit and included load terminals, installation stays straightforward—no extra parts, no unnecessary adjustments. It’s simply a dependable replacement that does what it’s supposed to do.
