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》
GB10222《Common technical requirements standard of high voltage switch equipment and control equipment》
GB311.1-6《insulation coordination of high voltage electric transmission and transformation equipment》

- Q: s the MCB switch a circuit breaker or a component on the circuit breaker?
- with leakage protection This function is used in the total switch circuit breaker or used in the branch circuit breaker better, personal understanding of the total circuit breaker
- Q: How to distinguish between disconnectors, circuit breakers?
- Because it does not have a special arc extinguishing device, can not cut off the load current and short circuit current.
- Q: How is the circuit breaker connected to the circuit system diagram?
- Circuit breaker: with over-current, short-circuit automatic trip function, with degaussing arc extinguishing device, can be used to connect, cut off the high current;
- Q: Why the high-voltage circuit is equipped with isolation switch and circuit breaker
- The disconnector has a clear break point, but only acts as an isolated circuit and can not be operated when the line has current. When disconnecting the circuit, be sure to disconnect the circuit breaker and disconnect the disconnector.
- Q: Isolation switch, circuit breaker, open the three What is the difference between ah
- Because it is through the air as a medium for the arc so called air-type low-voltage circuit breaker referred to as air switch, we usually home building power distribution is basically the air switch
- Q: Circuit breaker main circuit control power, how to wiring?
- Otherwise you should use a larger capacity circuit breaker or technical transformation, reduce the installation of short-circuit capacity. Or on the circuit breaker capacity transformation
- Q: Is there a sequence of circuit breakers and disconnectors?
- and there is no problem. After the circuit breaker, the circuit breaker has the ability of interrupting,
- Q: Circuit breaker generally choose what ah?
- Leakage protection is protected by a relative leakage or electric shock current that occurs within the detected grid and is fully protected as a trip signal and electrical trip task.
- Q: The difference between air switch and circuit breaker
- So the air circuit breaker can also fault in the state (load short circuit, load over current, low voltage, etc.) cut off the electrical circuit
- Q: The specific function and operation mode of the auxiliary switch on the circuit breaker switch
- can be through the auxiliary contact circuit breaker Split position, to achieve automatic control (even jump, BZT, mutual latch, start and stop protection, and so on).
