CH370 - 70Amp Circuit Breaker Description
CH370 - 70Amp Circuit Breaker
The CH370 is a 70 Amp, 3-pole CH plug-on circuit breaker used in compatible CH panelboards. It’s a common choice for three-phase circuits that sit in the mid-to-upper load range and still need reliable, everyday protection.
You’ll usually run into this breaker in HVAC systems, larger pumps, compressors, and other motor-driven equipment running 240V three-phase power. When replacing it, it’s typically a simple swap—CH type, 3 poles, 70 amps, plug-on style—so it fits right back into the same spot in the panel.
This breaker is rated for 240VAC systems, with a 10kA interrupting rating at 240VAC. It uses a thermal magnetic trip, which is standard for handling overloads and short circuits in branch circuit protection.
The plug-on design keeps installation quick and clean in compatible CH panelboards. Once installed, it provides a solid connection and dependable protection for three-phase circuits under normal operating conditions.
