Product introduction:
JCZR16-7.2J(D) series vacuum contactor-fuse combination appliance is suitable for three-phase AC power system with rated voltage of 3.6-7.2kV and rated frequency of 50Hz. It can be installed in the switch cabinet to form F-C circuit and used in conjunction with the integrated protector. It can be used by power plants and industrial and mining enterprises to close and disconnect AC high-voltage motors, transformers, induction furnaces and other loads, and has the function of overload and short-circuit protection.
Product features:
1. The chassis, contactor, base and fuse are arranged in a building block style, which is simple to debug and assemble;
2. During the debugging process of the contactor, only one parameter of overtravel needs to be adjusted to meet the requirements of the mechanical characteristics of the contactor. There are few adjustment links and the influence of human factors is avoided;
3. The adjustment is convenient. By changing the opening spring force, the influence of altitude on the self-closing force of the arc extinguishing chamber can be corrected.
