Cutler-Hammer HFD3030 U Molded Case Circuit Breaker

The Cutler-Hammer HFD3030 is a molded case circuit breaker intended for industrial power distribution applications requiring overcurrent protection for essential infrastructure. Specifically rated at 30 amperes and configured for 480-volt alternating current circuits, this unit features a fixed three-pole arrangement suitable for balancing load across multiple electrical phases in three-wire systems. Commonly deployed within commercial and manufacturing facilities, this breaker interrupts dangerous fault currents to protect wiring and connected machinery from thermal or magnetic stress on sensitive equipment or cabling infrastructure. Installation relies on panelboard systems constructed to accommodate the HFD series frame dimensions, ensuring secure mechanical mounting within enclosed electrical switchgear setups. Defined by its substantial enclosed body construction, the component maintains integrity during short-circuit events while providing manual switching capabilities to isolate branch circuits during routine maintenance or emergency activations.
