Eaton / Cutler-Hammer HLA3300 – 300A 3 Pole Molded Case Circuit Breaker Brand New

Built to handle demanding electrical loads, this Mark 75 L-Frame breaker supplies 300 amps of continuous power with standard long-time and instantaneous trip functions. It fastens securely into compatible Eaton Series C panelboards and serves as an exact fit for older Westinghouse L-Frame infrastructure. Capable of clearing 35kA faults at 480V, the unit utilizes an interchangeable trip mechanism, allowing facility managers to adapt protection parameters without replacing the entire breaker.
