1.Application

GSZ2-Y series of  Magnetically latched DC contactor is mainly used in DC working voltage is up to 48V, working current is 100A-400A circuit, for making and breaking ciruit. The product is mainly used in communication power supply, uninterrupted power supply system,also can be used for electrocar, low voltage converter, engineering machinery and otheruse of DC power occasion.

2. Structure feature

Action agency is directly operated type, contact s double breakpoints bridge type contact;

Main circuit wirig should match round or mouth type cold preaaing terminals;

can be equipped with one open and one closed auxiliary contacts, model for F4-11;

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 conservtion and durable;

when coil A1 terminal through control source positive pole contact closed,when A2 terminal through control source positive pole contact open.
