Product Data: Monitoring Current: 0.2–30A AC Contact Capacity: 0.3A @ 240V AC/DC Perforation Line 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% Shell Color: Black/Blue Features: Mutual inductance current monitoring with input-output security isolation and 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. Housing made of environmentally friendly, flame-retardant PC material. Operating Principle: Normally Open (M3050): When the perforation line current exceeds the set value, the red light turns on and the output signal closes; when the current is below the set value, the green light turns on and the switch opens. Normally Closed (M3056): When the perforation line current exceeds the set value, the green light turns on and the output signal opens; when the current is below the set value, the red light turns on and the switch closes. Package Includes: 1 x Current Detection Switch Induction Relay
