Westinghouse BAB3015H Bolt-On Circuit Breaker

The Westinghouse BAB3015H Bolt-On Circuit Breaker is a 3-pole, 15-amp, 240-volt device designed for dependable overload and short-circuit protection in three-phase power distribution systems. It mounts bolt-on in distribution panels, motor control equipment, and electrical service applications across commercial and industrial facilities, supporting replacement, retrofit, and panel upgrades. This BA-type breaker uses a standard thermal-magnetic trip to protect panelboards, industrial control systems, manufacturing equipment, and motor branch circuits. Common replacements include Eaton BAB3015H, Square D QOB315, and Siemens BQ3B015, reflecting cross-compatibility within standard three-pole bolt-on frames.
