Overview

The zw8-12/T outdoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is used in three-phase power systems with AC 50HZ and voltage 10-12KV. It is used to break and close load current, and has overload and short-circuit protection functions.

Using vacuum arc extinguishing, it has strong breaking capacity, long electrical life and mechanical life of 10,000 times.

Simple structure, maintenance-free and long maintenance cycle;

Good insulation performance and strong anti-pollution ability;

Can be equipped with spring or electromagnetic operating mechanism, with reliable mechanical performance and frequent operation; no fire and explosion hazards;

The built-in current transformer has a measurement accuracy of 0.2 and can realize three-phase differential protection;

A built-in suspected exposure controller can protect the circuit breaker from operating reliably under a certain temperature and humidity.

Operating environment conditions

a. Ambient air temperature: upper limit +40℃, lower limit -30℃ (general areas), -40℃ (alpine areas);

b. Altitude: ≤1000m (if the altitude needs to be increased, the rated insulation level will be raised accordingly);

c. Wind pressure: no more than 700pa (equivalent to wind speed 34m/s);

d. Amplitude: earthquake intensity does not exceed 8 degrees;

e. Pollution level: Level III;

f. Maximum daily temperature difference; not exceeding 25℃.
