ZW20A-12F

OUTDOOR HIGH-VOLTAGE INTELLIGENT
BOUNDARY VACUUM CIRCUIT BREAKER

Overview
ZW20A-12F outdoor high-voltage intelligent boundary vacuum circuit breaker is outdoor high-voltage switchgear with rated voltage of 12kV and three-
phase AC 50Hz. Mainly used for breaking and closing the load current, overload current and short circuit current of the power system.
It is suitable for the protection and control of substations, industrial and mining enterprises, and urban and rural distribution networks, especially
for places with frequent operations and urban network automatic distribution networks. This product is matched with the controller, can meet the
requirements of the distribution automation system, and can reliably and effectively complete the traditional recloser function. It adopts a mature box
seal structure, filled with SF6 gas, has good sealing performance, so that it is not affected by the external environment, is a maintenance-free product.
The spring operating mechanism adopts a direct-acting chain main drive and a multi-stage tripping system. The action reliability is high, and it is a good
product for the circuit breaker on the column.
