Product Description Description: Product datas： Monitoring current: 0.2-30A AC Contact capacity: 0.3A@240V AC/DC The diameter of the perforation line: 10MM Dimensions: 65*25*47MM Maximum leakage value: 0.1MA Maximum overload capacity: 100% Operating temperature: -20－55℃ Hysteresis: less than 1% The shell color: black/blue >Mutual inductance current monitoring, security isolation of input and output, self power >The range of the monitored current is up to 30A;the monitoring threshold is adjustable within 0.2-30A. >Hysteresis is less than 1%. It can be used instrong magnetic environment. >Non-contact electronic switch with fast reaction and unlimited number of on-and-off operations. >The shell is made of environmentally-friendly flame-retardant PC material. Specifications: Operating principle： Normally open: M3050 When the current of the perforation line exceeds the set value, the red light turn on and the output signal close; when the current is below the set value, the green light turn on and the switch open. Normally closed: M3056 When the current of the perforation line exceeds the set value, the green light turn on and the output signal open ; when the current is below the set value, the red light turn on and the switchs close. Package Included: 1*Current detection switch induction relay
