CAH3125W - 125Amp Circuit Breaker

CAH3125W - 125Amp Circuit Breaker

When you're replacing a breaker in an existing system, compatibility is usually the first thing on your mind. The CAH3125W 125 Amp 3-Pole Molded Case Circuit Breaker is commonly used in commercial and industrial electrical equipment where matching the original specifications is important. If your system was built around a CAH-frame breaker, having the right amp rating, pole configuration, and physical dimensions can help make a replacement project much more straightforward.

Rated for 125 amps with a 22kA interrupting capacity at 240VAC, the CAH3125W is equipped with a non-interchangeable trip unit and is supplied without lugs installed. That makes it a practical option for applications where connection hardware is selected separately to meet the requirements of the equipment. Its compact CAH-frame design allows it to fit installations built around this breaker style, while the 40°C ambient rating supports use across a wide range of commercial and industrial environments.

Many facilities continue to operate electrical infrastructure that has been serving reliably for years. When maintenance or repairs become necessary, finding a breaker that matches the existing setup can save time and help avoid unnecessary modifications. Built to last and intended for form, fit, and functional replacement, the CAH3125W helps keep compatible electrical distribution systems operating as intended.
