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:Circuit problem! Hurry Miniature Circuit Breaker!
- After removing the above problems, you can turn off all the electrical equipment or pull out the plug, such as the circuit breaker also jump
- Q:How to choose a circuit breaker for home and small office circuits
- When overload or short circuit, the small circuit breaker handle, the leakage attachment handle does not move. When the leakage occurs, both handles are activated.
- Q:Household leakage circuit breakers, circuit problems
- do not know how the points. Maybe 2P, but I do not know. Four holes, up and down two, how to take this
- Q:Home circuit breakers and how much air is open
- the principle of air switch, the function of the general situation for the customer matching distribution box in the process, should be in a small lighting, socket, air conditioning large matching principle
- Q:Discussion on the Selection of Circuit Breaker in Low Voltage Circuit
- especially in recent years, single-chip technology applications, Frame circuit breakers toward high performance, easy maintenance, network direction.
- Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
- You said the knife can be understood as a kind of isolation switch, it is only as a circuit break point, no lines, load protection function
- Q:Is the circuit breaker in the circuit necessary?
- when the current is slightly larger, will only cut off the other two phase to produce too much electric current Arched open
- Q:Isolation switch, circuit breaker, open the three What is the difference between ah
- The full name of the air switch is an air type low voltage circuit breaker belonging to the circuit breaker which is mainly used in low voltage circuit
- Q:Does the isolator and circuit breaker able to switch to each other?
- When the circuit breaker disconnect the live circuit, the internal contact in the separation of the moment will produce an arc, the higher the voltage or the greater the current, the stronger the arc.
- Q:What is the length of time that the circuit breaker can delay?
- The tripping characteristic curve of the related product can be found in the corresponding relationship between the specific trip time and the overload current
