The Siemens 3LD3150-0TK13 is a 3-pole SENTRON 3LD3 series load break switch designed for use as a main switch, maintenance/repair switch, safety switch, and emergency-stop device. It features a red/yellow rotary (knob) actuator with 48 x 48 mm front-plate dimensions and is intended for front mounting via a 22.5 mm central-hole fixing. With a rated operational current (Iu) of 25 A and an operational power of 9.0 kW at AC-23 A / 400 V, it is suitable for safely disconnecting three-phase motors, HVAC systems, and the electrical equipment of small machines such as saws, compressors, pumps, concrete mixers, drills, milling machines, and woodworking equipment. The modular design allows quick addition of auxiliary switches, N-PE terminals, or a 4th pole, and the rotary handle can be padlocked for safe isolation.
