Structure Features
1. The contactor is composed of arc-extinguishing system, contact system, base frame and magnetic system (including iron core, coil).
2. The contact system of the contactor is of direct action type and double-breaking points allocation.
3. The lower base-frame of the contactor is made of shaped aluminum alloy and the coil is of plastic enclosed structure.
4. The coil is assembled with the amarture to be an integrated one. They can be directly taken out from or inserted into the contactor.
5. It is convenient for user’s service and maintenance.
