The LMLB1-1RLS4-52-50.0-1-01-V is a single-pole hydraulic-magnetic circuit protector engineered for precise DC circuit control and overcurrent protection. It is rated for 50.0 amperes and features a DC long delay curve (delay 52), making it suitable for circuits with moderate inrush currents. A key feature is the mid-trip handle, which moves to a central position upon electrical overload for rapid fault identification. This model includes a series trip configuration with an integrated alarm switch and electrical trip capability, and uses a silver 5/16-inch bullet terminal for the main connection. Being VDE and CCC approved, this protector is ideal for demanding applications in telecommunications, industrial controls, and DC power distribution systems.
