Overview
The Eaton Cutler-Hammer HMCPS030H1C is a 30-amp, 3-pole motor circuit protector engineered for safe motor control and protection. This Series C molded case circuit breaker combines magnetic instantaneous trip technology with a thermal-magnetic range of 90–300A, making it ideal for motor starter assemblies that use electronic overload relays. With 600VAC rating and 65kAIC interrupting capacity at 480V, the HMCPS030H1C is UL 489 and CSA 22.2 certified.
