Hassle-Free Returns Eaton / Cutler-Hammer BAB2040S – 40A 2 Pole Miniature Circuit Breaker

Built for commercial and industrial applications, the Eaton BAB2040S is a 40A, two-pole miniature circuit breaker. It integrates standard thermal-magnetic protection with a factory-installed shunt trip mechanism, allowing the breaker to be tripped remotely via a 120/208/240VAC signal. The bolt-on configuration is engineered for Eaton Pow-R-Line, Cutler-Hammer, Westinghouse, Bryant, and Challenger panelboards. It effectively replaces older QNBL2040S and QB2040S models.
