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》

- Q: s the MCB switch a circuit breaker or a component on the circuit breaker?
- The determination of the total switch circuit breaker in the household distribution box is determined by the sum of the rated current of all the branch circuit breakers in the distribution box
- Q: Is the circuit breaker in the circuit necessary?
- occasionally short-time overcurrent motor can withstand, but the fuse blown, but also affect the production.
- Q: How is the total switch breaker in the distribution box correctly
- protection current in the grid after the protection, then the command will be the leakage protector trip occurs when the control of the main circuit breaker trip
- Q: Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
- the current flows through the LED When the GPRS high, the emission junction reverse bias, collector junction reverse bias, work in the cut-off area
- Q: What is the difference between open air and circuit breakers?
- The first two kinds of protection for the basic configuration of the air circuit breaker, the latter two for the optional function. 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: How is the circuit breaker different from the air circuit breaker?
- Upstairs said the air switch is a kind of circuit breaker. The switch is a switch that can turn on and off the load current; the disconnector is an electrical device that isolates the power supply and can not turn on and off the current (except for the voltage)
- Q: Is the zero line going through the circuit breaker?
- Three-phase three-wire, the use of protection to zero system, the zero line is absolutely not allowed to go through the circuit breaker, because the zero line is broken,
- Q: How is the circuit breaker connected to the circuit system diagram?
- Let's talk about the circuit breaker and the open circuit breaker. The following explains the difference between the disconnector and the circuit breaker.
- Q: Circuit problem! Hurry Miniature Circuit Breaker!
- Circuit breaker trip and leakage instructions do not pop up, indicating that the leakage is not a jump or jump
- Q: The specific function and operation mode of the auxiliary switch on the circuit breaker switch
- circuit breakers and disconnectors of the electrical latch circuit and all low-voltage circuit.
