MZZ (1) -12/M630-20 outdoor high-voltage permanent magnet vacuum circuit breaker (recloser/sectionalizer) is an outdoor high-voltage distribution device with three-phase AC 50HZ, rated voltage 12V, rated current 630A-1250A, and short-circuit current 16KA-20KA. Mainly used for breaking and closing load current, overload current, and short-circuit current in power systems. Suitable for protection and control in power distribution systems of industrial and mining enterprises, and more suitable for rural power grids and places with frequent operations. This product retains all reasonable parts and excellent performance of the original ZW32 structure, and also increases the overall mechanical life of the arc extinguishing chamber by several times compared to the original mechanical life, with a lifespan of up to 60000 times and 30000 times without maintenance during the service life. It can be easily expanded to form reclosers and segmenters, which are used to distinguish between permanent and temporary faults. At the same time, the powerful control function of the permanent magnet mechanism controller can be utilized to achieve various networking, protection, and operation functions according to customer requirements.

Structural characteristics of MZZ (1) -12/M630-20 outdoor high-voltage permanent magnet vacuum circuit breaker:
1. The microcomputer control device is equipped with a set of 20 batteries, and the battery capacity can support 50 hours of operation after a power outage.
2. The battery charging adopts electronic PT, AC220V, or CT charging, which is safe and reliable.
3. The device has the function of on-site remote control switch on/off operation, with a remote control distance of 30 meters, and on-site operators do not have the difficulty of climbing power poles.
4. Provide protection setting management function, users can freely modify the tripping current, and the setting value is flexible.
