              Special Contactor for Capacitor Matching
              MC series
              Summary

              MC contactor is specially designed for switching capacitors. It is equipped with advanced closed contacts. First, the auxiliary contacts guide current through the series of advanced closed contacts to ensure that the input current is within acceptable range. This stage takes 2-10 Ms. Then the main contact closure contacts connect the capacitor to the circuit completely, and the auxiliary contacts are automatically disconnected (the over-current intensity of 2.5 and 5 kV Ar models is ensured by special strengthening contact material).

              Note: When the switch is switched on, it must be discharged first (the maximum residual voltage of the terminal is less than or equal to 50V) to prevent short circuit. The current of the gG fuse must be 1.5~2 times of the rated current.

              Summary
              SC series dynamic switching contactors are used in systems with rapidly changing loads. After using SC series dynamic contactors, the switching time of capacitors used to provide capacitive power to the system is less than 20 ms (1 cycle), which can bring more effective compensation for switching load quickly, such as flat head welder, crane and arc furnace.
