Mutual inductance current monitoring with input and output security isolation and self-powered design. Monitored current range up to 30A with adjustable monitoring threshold between 0.2A and 30A. Hysteresis less than 1%. Suitable for use in strong magnetic environments. Non-contact electronic switch offers 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: <1% Operating principle: Normally open (M3050): When the current in the aperture exceeds the set threshold, the red LED turns on and the output closes. When the current drops below the threshold, the green LED turns on and the switch opens. Normally closed (M3056): When the current in the aperture exceeds the set threshold, the green LED turns on and the output opens. When the current drops below the threshold, the red LED turns on and the switch closes. Color: As shown Material: Plastic Package includes: 1 x Current detection switch induction relay Note: Lighting and display differences may cause slight color variations between the image and actual item. Measurement tolerance: ±1–3cm.
