Detailed introduction

High Voltage Vacuum Contactor

JCZ5-7.2KV Vacuum Contactor

General Description:
VCZ5-7.2,12/400,630 series vacuum contactor is used in an AC. 50-60 Hz electric power system, with rated working voltage is 7.2Kv and 12kV, and rated current of 400A,630A, for direct or romote on-off control and circuit-breaking control of the of the main load. It is especially suitable for the frequently operated electric control applications such as electric motors, transformer, etc. This series adopts integrated framework, before-and-after layout between the main circuit and controlling circuit, adopts electrical latch or machanical latch, and vacuum interrupter with ceramic shell.
