BW2125 - 125Amp Circuit Breaker Description

BW2125 - 125Amp Circuit Breaker

The BW2125 is a 125 Amp, 2-pole main residential circuit breaker designed for 240-volt electrical service applications. Commonly installed as the primary disconnect and overcurrent protection device in residential electrical panels, it helps protect your electrical systems from overloads and short circuits while supporting the power requirements of modern homes.

With a 125 Amp rating and a 10kA interrupting capacity at 240 VAC, the BW2125 is frequently used in residential service equipment, panel replacements, service upgrades, and new construction projects. Its two-pole design allows it to disconnect both legs of the electrical service when required, making it suitable for main breaker applications where full system disconnect capability is needed.

The compact footprint allows installation in compatible equipment without sacrificing panel space.

Whether your replacing an existing main breaker or completing a panel upgrade, the BW2125 provides the ratings and functionality commonly required in residential electrical service applications.
