Mutual inductance current monitoring with security isolation between input and output. Self-powered design. Monitored current range up to 30A; monitoring threshold adjustable within 0.2–30A. 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: 0.2–30A 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: less than 1% Operating principle: Normally closed (M3056). When the current in the aperture exceeds the set threshold, the green LED turns on and the output signal opens. When the current drops below the set threshold, the red LED turns on and the switch closes. Color: As shown Material: Plastic Package contents: 1 x Current detection switch induction relay Note: Lighting and display settings may cause slight variations in color between the image and the actual item. Measurement error allowance: ±1–3cm.
