Use this contactor from Siemens to reliably switch power to devices like your load feeder. It ensures the safe switching of a high-current capacity electrical circuit, so there's minimal risk of equipment damage or arcing to motors, even if they're frequently stopped and started. Space-saving dimensions of 85 (H) x 45 (W) x 107mm (D) mean the unit is compact and easy to integrate into your control cabinet. For safety, its front face is protected against human touch and wires or tools larger than 12mm. This contactor is suitable for switching power to electric motors used with equipment such as conveyors, hoists and machine tools.
