Eaton Cutler-Hammer SPCL1C16 DIN Rail Circuit Breaker

The Eaton Cutler-Hammer SPCL1C16 is a DIN-rail mounted, single-pole circuit breaker rated for 277 VAC and 16 A. Identified as SPCL1C16, it belongs to Eaton’s SPCL family and uses a Type SPCL trip characteristic with a C-type curve. This 1P device is designed to protect a 1-phase branch circuit in electrical panels or control enclosures that accept DIN rail-mounted protection devices. With a 16 A maximum load current and 277 VAC operating voltage, it provides overcurrent protection for circuits in commercial and light-industrial installations that use 277 V single-phase supplies. The unit is intended for installation on standard DIN rails and integrates with other SPCL-series breakers within a modular panel setup. Its 1-pole, 16 A, 277 VAC configuration clarifies its role as a compact protective device for small distribution blocks within a DIN rail ecosystem.
