CH330 - 30Amp Circuit Breaker Description
CH330 - 30Amp Circuit Breaker
The CH330 is a 30 Amp, 3-pole CH plug-on circuit breaker used in compatible CH panelboards. It’s a very common size for lighter three-phase circuits where you still want solid, dependable protection without going overboard on capacity.
In the field, you’ll usually find this breaker in HVAC equipment, small pumps, compressors, and control panels running 240V three-phase power. When you're replacing one, it’s typically a simple match—CH type, 3 poles, 30 amps, plug-on style—so it fits right back into the same spot and works the way it should.
This breaker is rated for 240VAC systems, with a 10kA interrupting rating at 240VAC. It uses a thermal magnetic trip unit, which is standard for protecting branch circuits from overloads and short circuits.
The plug-on design makes installation quick in compatible CH panelboards.
