Eaton HFD3020L Three Pole Molded Case Circuit Breaker

The Eaton HFD3020L is a three-pole molded case circuit breaker (MCCB) used to protect electrical circuits in three-phase distribution systems. It is rated for 20 amperes and up to 600 volts, providing overcurrent protection for feeders and branch circuits in commercial or industrial panel boards. This unit reflects the Cutler-Hammer/Westinghouse lineage now under the Eaton name, and its HFD3020L designation identifies a 3-pole, 20-A, 600-V MCCB configuration. In three-phase installations, its three poles interrupt simultaneously to help maintain balance and safety, making it suitable for compact, reliable protection within compatible molded-case panel assemblies. Typical environments include commercial electrical rooms, light industrial panels, and equipment feeders.
