TZW32F – 12, outdoor intelligent vacuum circuit breaker complete set, is an intelligent complete set based on the outdoor vacuum circuit breaker. The device is mainly composed of the ontology of a vacuum circuit breaker of TZW32F – 12 and a TF intelligent demarcation switch controller. It is installed at the point of common coupling of distribution power line users’ service wire at the 10 KV voltages, and it can also be installed in a branch circuit or the end of subscriber line that meets the requirements. It realizes earth fault current, over fault current detection function, perfectly protects control function and “three teles” communication function (configuring communication backend software). After the equipment is installed and put into operation, it is able to automatically remove the single-phase earth fault of the controlled branch line and automatically remove the same short-circuit fault of the controlled branch line of the circuit breaker to improve the reliability and automotive level of power supply.
Outdoor intelligent vacuum circuit breaker of TZW32F – 12 is widely used in various distribution fields such as substations, industrial and mining enterprises, protection and control of urban and rural networks, automatic distribution networks and frequent operations of city and country, etc.
This circuit breaker has the characteristics of small size, light weight, anti-condensation and maintenance-free, and can adapt to harsh weather conditions and pollution environment.

This type of product operates with a permanent magnet operating mechanism; since the permanent magnet operating mechanism provides the holding force by the permanent magnet, the switch is kept in the opening and closing position. The number of mechanical parts is small, and the mechanical segment is rotated, thereby greatly improving the reliability and mechanical endurance of the switch.
