Eaton Corporation CHB330 Circuit Breaker 3P 30A 240V

Eaton Corporation’s Cutler-Hammer CHB330 3P 30A 240V circuit breaker is a three-pole device rated for 30 amperes at 240 volts. The CHB330 model designation identifies it as part of Eaton’s CHB line designed for protecting three‑phase electrical circuits. In practical use, it is intended for 240V, three‑phase distribution panels, where it provides overcurrent protection for conductors and equipment connected to each of the three phases. Each pole carries an individual circuit path, and the 30A rating corresponds to the maximum continuous current the breaker will allow before tripping, helping to prevent wiring insulation damage and equipment failure within the installation’s design limits.
