Prouduct Details
Latching relay is a new type of relay which uses magnetic principle to control circuit's on and off. Its normally open and closed state are provided completely by permanent magnet steel'working and completed the conversion of on-off state base on the triggering of a certain width pulse signal.
IM1201T is a three-phase latching relay. As a three-phase power latch relay, it has stable performance and long service life. The latch relay switch has the following characteristics:
Three poles contact(normally open, normally closed) three way control
Maximum switching current 120A, strong load capacity; single/dual coil optional
CT Assembled, Low Consumption, Pulse Driving, Environment-friendly
Our latching series relay are specifically made to cater for the requirements of smart meters, typical features include:
Compact in size
Low cost and very competitive price
Pulse coil driven with negligible energy consumption
Choices of single and dual coils
Very low temperature rise and minimal coil heat
Magnetic immunity and anti-tempering
Long mechanical and electrical life
Single phase models and polyphase models (with double-pole and three-pole relays available)
Wide range of contact current ratings (60A to 200A)
Meeting various international standards (e.g. UC3 )
Customised assemblies with stranded wires, brass terminals, CTs, shunts and even meter cases
