High Voltage Vacuum Circuit Breaker , Outdoor Pole-mounted Vacuum Breaker

General

ZW20A-12 Outdoor Pole-mounted Vacuum Circuit Breaker is a kind of outdoor distribution equipment, three-phase, AC50Hz, with rated voltage of 12kV. It is mainly used in power distribution network to break, open and close load current, overload current and short-circuit current. It is also used in substation, industrial and mining enterprises, urban and rural power grid for control and protection. And it is more suitable for frequency operation and the urban distribution automation network.

Model meaning:
Z W 20 A - 12 / T - 0 0
Z: vacuum circuit breaker
W: Outdoors
20A: Design Number
12: Rated voltage (KV)
T: spring operating mechanism
0: Rated current (A)
0: Rated short-circuit breaking current (kA)

Environmental Conditions

1. Altitude: ≤1000m; if applied in special conditions, it is designed to 2000m to 4000m to meet the requirements of different altitudes.
