Zw32-12LJ Prepaid integrated circuit breaker on outdoor column is outdoor power distribution equipment with rated voltage 12Kv and three-phase AC 50Hz. It is mainly used to open and close the load current, overload current and short circuit current of high voltage metering users, and has metering and prepayment functions at the same time. Suitable for urban and rural end users for protection and control purposes.

Zw32-12jl /630 Prepaid circuit breaker rated current 630A(can also be produced according to customer requirements), rated short-circuit breaking current 25KA, with the controller can cut off the normal load current, at the same time as transformer backup protection can cut off the short-circuit current.

  In order to meet the needs of modern electricity management, the problem of arrears of users and line loss can be solved by means of science and technology. Our company developed a new set of 10KV high voltage prepaid metering device. This device is suitable for high voltage metering users between each transformer capacity grade, using the device can achieve a variety of relay protection, and has the characteristics of high accuracy, stable operation, low cost.
