Monitoring current range: 0.2-30A AC Contact capacity: 0.3A@240V AC/DC Hole diameter for conductor: 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% Housing color: black/blue Features: Mutual inductance current monitoring with electrical isolation between input and output; self-powered design. Adjustable monitoring threshold within 0.2A to 30A. Low hysteresis ensures stable operation; suitable for use in strong magnetic environments. Non-contact electronic switch enables fast response and unlimited switching cycles. Housing made of environmentally friendly, flame-retardant PC material. Operating principle: Model M3050 (Normally Open): When the detected current exceeds the set threshold, the red LED illuminates and the output contact closes. When the current drops below the threshold, the green LED turns on and the contact opens. Model M3056 (Normally Closed): When the detected current exceeds the set threshold, the green LED illuminates and the output contact opens. When the current drops below the threshold, the red LED turns on and the contact closes. Package includes: 1 x Current detection switch induction relay
