Relay switch Mutual inductance current monitoring, secure isolation of input and output, self-powered 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 Wire pass-through hole 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 (Model: M3056) When the current through the pass-through wire exceeds the set threshold, the green indicator light turns on and the output signal opens; when the current drops below the set threshold, the red light turns on and the switch closes Color: As shown in image Material: Plastic Package includes: 1 x Current detection switch induction relay Note: Other items not included Note: Lighting and display differences may cause slight color variation between image and actual item. Measurement tolerance: ±1–3cm
