Product Data: Monitoring Current: 0.230A 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: -20C to 55C Hysteresis: Less than 1% Housing Color: Black/Blue Features: - Mutual inductance current monitoring with electrical isolation between input and output; self-powered design - Monitored current range up to 30A; adjustable monitoring threshold within 0.230A - Hysteresis less than 1%; suitable for use in strong magnetic environments - Non-contact electronic switch with fast response and virtually unlimited switching cycles - Housing made of environmentally friendly, flame-retardant PC material Operating Principle: Normally Open (Model M3050): When the current in the conductor exceeds the set threshold, the red LED turns on and the output contact closes. When the current drops below the threshold, the green LED turns on and the contact opens. Normally Closed (Model M3056): When the current in the conductor exceeds the set threshold, the green LED turns on 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 Sensing Switch Relay
