The Eaton Cutler-Hammer LD3600A02S21 molded case circuit breaker provides reliable AC and DC protection for industrial and commercial electrical systems. Built on the LD frame platform, this breaker features a thermal magnetic interchangeable trip unit to safeguard circuits against overloads and short-circuit faults. Rated at 600 amperes with a 3-pole configuration, it supports AC systems up to 600VAC and DC systems up to 250VDC. The model includes the A02 auxiliary switch option (1-A open / 1-B closed, left pole mounted, exiting rear) for advanced signaling, as well as the S21 shunt trip option (12–24 VAC/VDC, right pole mounted, exiting same side) for remote tripping control. With high interrupting capacity, this breaker is ideal for industrial, commercial, and renewable energy applications. The bolt-on design ensures secure panel installation, and aluminum line and load end terminals are standard.
