Cutler-Hammer CH320U Molded Case Circuit Breaker

The Cutler-Hammer CH320U Molded Case Circuit Breaker is a three-pole (3P) protective device rated for 20 amps at 240 volts, designed to guard circuits inside distribution panels and equipment enclosures. This CH320U carries a 10K rating, indicating its interrupting capacity for fault currents at 240V within its MCCB class. As a molded case breaker, it supports straightforward replacement in compatible Eaton Cutler-Hammer installations and forms part of standard multi-pole protection schemes used in commercial electrical distributions. Typical applications include branch-circuit protection for lighting, receptacle circuits, and small motors in commercial or light-industrial settings where a compact 3P protective device is required.
