The Westinghouse HFA3010 is a 3-pole molded-case circuit breaker rated for 10 A at up to 600 VAC, designed for industrial electrical distribution and branch-circuit protection. With thermal-magnetic protection, it interrupts overcurrent and short circuits for low-amperage three-phase equipment and is commonly installed in MCCs, switchboards, motor control centers, and automation systems. It can be panel- or switchboard-mounted and is used in power distribution and motor control systems operating at 50/60 Hz. Common replacements include Eaton HFA3010, Siemens HFD3010, and Square D LA3610.
