Mutual inductance current monitoring with security isolation between input and output; self-powered design. Monitored current range up to 30A; monitoring threshold adjustable within 0.230A. Hysteresis less than 1%; suitable for use in strong magnetic environments. Non-contact electronic switch with fast response and unlimited switching cycles. Enclosure made of environmentally friendly, flame-retardant PC material. Monitoring current: 0.230A AC Contact rating: 0.3A @ 240V AC/DC Aperture wire diameter: 10mm Dimensions: 65 x 25 x 47mm Maximum leakage current: 0.1mA Maximum overload capacity: 100% Operating temperature: -20C to 55C Hysteresis: less than 1% Operating principle: Normally closed (M3056 model) When the current through the aperture exceeds the set threshold, the green LED turns on and the output signal opens. When the current is below the set value, the red LED turns on and the switch closes.
