CH350 - 50Amp Circuit Breaker

CH350 - 50Amp Circuit Breaker

The CH350 is a 50 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-range of load requirements, especially where consistent protection is needed without stepping up to larger frame sizes.

In everyday use, this breaker is often found in HVAC systems, pumps, compressors, and general motor circuits running on 240V three-phase power. When you're replacing one, it’s usually a straightforward match—CH type, 3 poles, 50 amps, plug-on style—so it fits right back into the same position in the panel.

This breaker is rated for 240VAC systems, with a 10kA interrupting rating at 240VAC.

The plug-on design keeps installation simple in compatible CH panelboards. Once installed, it provides a secure connection and reliable protection for three-phase circuits under normal operating conditions.
