The Eaton HFD3040 is a 3-pole molded-case circuit breaker (MCCB) rated for 40 amps at up to 600 volts, designed to protect three-phase circuits. It features a shunt-trip mechanism for remote tripping, enabling fast shutdown from a separate control point. This device provides overcurrent protection in electrical distribution systems where a compact MCCB form factor and remote trip capability are required.
