CH3015 - 15Amp Circuit Breaker

CH3015 - 15Amp Circuit Breaker

The CH3015 is a 15 Amp, 3-pole CH bolt-on circuit breaker used in compatible CH panelboards and electrical distribution equipment. It’s the type of breaker you’ll typically see in commercial and industrial systems where a small three-phase load needs dedicated protection.

In real-world use, breakers like this are often tied into HVAC equipment, control circuits, small motors, pumps, and other auxiliary loads that run on three-phase power. When you're replacing one, it usually comes down to a few basics—matching the CH type, 3-pole layout, 15-amp rating, and bolt-on connection style to what the panel already calls for. The CH3015 is built for those exact situations.

This is a thermal magnetic breaker with a non-interchangeable trip unit, rated for 50/60Hz operation and designed to perform in 40°C environments. It carries a 14kA interrupting rating at 480VAC and 65kA at 240VAC, making it suitable for systems where available fault current needs to be properly managed. It is also HACR rated, which means it can be used in HVAC-related applications where listed protection is required.

The bolt-on design gives it a secure, solid connection inside compatible equipment—something that matters in panels that see constant vibration or continuous operation. Once installed in the correct CH-compatible system, it becomes part of the day-to-day electrical protection keeping smaller three-phase loads safely isolated from overload or fault conditions.
