General Description:
JCZ5-7.2,12/400,630 series vacuum contactor is used in an AC(50-60Hz) electric power system, with rated working voltage is 7.2Kv and 12kV, and rated current of 400A,630A, for direct or remote on-off control and circuit-breaking control of the main load.
It is especially suitable for frequently operated electric control applications such as electrical motors, transformers, etc. This series adopts an integrated framework, a before-and-after layout between the main circuit and the controlling circuit, electrical latch or mechanical latch, and a vacuum interrupter with a ceramic shell.
