Inductance current monitoring with security isolation of input and output, self-powered design. The monitored current range is up to 30A, adjustable within 0.2–30A AC. Hysteresis is less than 1%; suitable for use in strong magnetic environments. Non-contact electronic switch with fast response and high number of switching operations. Housing made of environmentally friendly, flame-retardant PC material. Monitoring current: 0.2–30A AC Contact rating: 0.3A @ 240V AC/DC Aperture diameter: 10mm Dimensions: 65 x 25 x 47mm Maximum leakage current: 0.1mA Maximum overload capacity: 100% Operating temperature: -20°C to 55°C Hysteresis: <1% Operating principle: Normally closed type (M3056) When the current through the aperture exceeds the set value, the green LED turns on and the output signal opens; when the current drops below the set value, the red LED turns on and the switch closes.
