Overview

Vacuum contactor uses vacuum interrupter to extinguish arc to frequently connect and cut off normal working current. It is usually used for 6-40.5kV system AC motor in long distance connection and disconnection.

Product Details

JCZ5-7.2/12 KV series high voltage out door circuit breaker can be used for 50HZ-40.5kv outdoor high voltage electrical equipment.

Product description

Attached spring operating structure and electromagnet operating structure can manipulate electric opening and closing in a distance, or accumulate energy for manual operation.

Mainly used in controlling and protection of outdoor power transmission and transformation system of 35kv, also in normal operation and short-circuit protection for all kinds of power grid and frequent operation place.

Highest system voltages Um related to the rated voltages are defined in IEC 60071-1.

These series of VCBs are ceramic pillar type.

Vacuum interrupter is installed in upper part of ceramic insulator.

It has characteristics of well tightness and high temperature endurance, non-combustion and non-exploration, easy mounting, anti-aging and long service life.
