CHB150 - 50Amp Circuit Breaker

CHB150 - 50Amp Circuit Breaker

The CHB150 is a 50 Amp single-pole breaker used in Eaton CH Loadcenters. It’s mainly used as a replacement breaker in existing CH panel setups where you need to match the original breaker type and keep everything consistent inside the panel.

In practice, this breaker is often found on higher-load 120V branch circuits, along with general-purpose circuits that require a 50 amp rating. Inside, it uses a thermal magnetic trip, which handles both overloads and short-circuit conditions during normal operation. It’s designed for standard branch circuit protection in systems already built around Eaton CH equipment.

The CHB150 is rated for 120/240V systems with a 10kA interrupting rating, and it’s commonly used in residential and light commercial panels where CH loadcenters are already installed. Most of the time, it’s selected simply because it matches what’s already in place and keeps the system unchanged.

These breakers are typically used in maintenance situations where the goal is simple—replace the breaker, keep the same configuration, and get the panel back in service without any adjustments.
