Product Introduction：
ZW32-24 outdoor high voltage vacuum circuit breaker（short for “circuit breaker”）is an outdoor power distribution equipment suitable for three-phase system of rated voltage12KV, AC 50Hz, to open and close the load current、overload current and short-circuit current in power system. It’s applicable to substations and industrial-mining enterprises, and conditions which need frequent operations, such as in rural nets.
This circuit breaker has characteristics of small volume、light weight、anti air condensation、free maintenance etc; it can work in bad weather and pollution environment.
Conforms to regulation of:
GBl984《AC high-voltage circuit-breakers》

- Q: Home no electricity corridor switch the total switch circuit burned how the matter
- here are two general reasons, one is the switch quality is not good, the second is the existence of the installation quality defects
- Q: he circuit breaker in the circuit mainly plays a protective element what protects the two functions of the element
- he circuit breaker is composed of a thermal element and a current coil, and when the circuit current exceeds the rated value
- Q: What is the solution of the leakage circuit breaker always jumping?
- may be caused by the wire. Leakage switch installed in the use of equipment before the better
- Q: Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
- which is equivalent to the collector junction and the transmitting junction connected, so that 5.0V and the transistor below the resistance R10 connected
- Q: What are the differences between switches and circuit breakers?
- And because of its arc extinguishing device and internal structure, he can also load with the gate
- Q: What is the difference between a circuit breaker and other switches?
- 630A the following circuit, the general use of molded case circuit breaker. Molded case circuit breakers are suitable for branch protection switches - engineers
- Q: How to distinguish between disconnectors, circuit breakers?
- It is a no arc device switch device
- Q: Why the high-voltage circuit is equipped with isolation switch and circuit breaker
- So the isolation switch installed in front of the circuit breaker, open, so that between the power supply and the circuit breaker has a clear point
- Q: Load switch, vacuum switch and circuit breaker
- Load switch: can safely cut off the load current, can not cut off the short circuit current
- Q: How to choose a circuit breaker for home and small office circuits
- The test button should be tested once a month to check the function of the leakage connector.
