TIANSHUI 213 ELECTRICAL APPARATUS CO.,LTD CODE
● Action agency is directly operated type,contact is double breakpoints bridge type contact
● Main circuit wiring should match round or mouth type cold pressing terminals
● Auxiliary contacts can be convenient loaded and unloaded
● Product is bistable state,contact with closing or opening position all caging by permanent magnet,big holding force,the product with good shock resistance
● Coil instant power on when need movement,doesn't need power on when normal maintain,coil energy conservation and durable
● When coil A1 terminal through control power supply positive pole contact is open,when A2 terminal through control power supply positive pole contact is closed
4.WORKING CONDITIONS AND INSTALLATION CONDITIONS
● Ambient air temperature is not more than+70°C，is no less than-40°C。
● When temperature is+40°C,relative air humidity is not exceeding 50%,with lower temperature higher relative humidity will be permitted，in 20 may up to 90%。By the temperature change to occasionally produce dews,should take special measure.
● When mounted position altitude exceed 2000 meters,every rise 500 meters down 10%use,highest do not exceed 4500 meters.
The pollution degree is"pollution degree 3".
