ZW10-12/630-20 series outdoor AC high-voltage vacuum circuit breaker is a three-phase AC 50Hz, outdoor high-voltage switchgear. It is mainly used in 12KV rural and urban power systems to open and close load current, overload current and short-circuit current. It can also be used in other similar places.
The circuit breaker can be equipped with an isolating switch to form a combination electrical appliance;
Can be equipped with a reclosing controller to form a recloser;
It can be combined with FTUs and RTUs to form an automated distribution network switch, clearing and isolating faults, automatically transferring power, and automatically restoring power. Through remote control devices, it can communicate with the DMS system of the distribution management center to achieve four remote functions.
When used with the smart IC card prepaid power distribution control box, it can realize automatic power off without charge and automatic power restoration when electricity is purchased, meeting the current power supply department's demand for power management reform.

Features
Special anti-condensation measures are adopted inside to ensure insulation inside the box;
The transmission method adopts patented technology, which is easy to install and reliable in operation, avoiding the impact of mechanical failure on the performance of the circuit breaker;
No oil filling, no air filling, small size, light weight, CT protection;
The operation can be electric or manual.
