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: What circuit symbols are used for circuit breakers
- mass I + I + I <phase = nine = 0. Mass or I + I + I <phase + = nine = 0. So the brothers must install the ground wire ah
- 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: 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: How to protect the leakage protector leakage protection?
- Also known as leakage relays are often used to maintain an important place for electricity. RCD principle for the use of zero sequence current
- Q: What is the difference between open air and circuit breakers?
- The type of protection function and the protection mode are selected by the user according to their needs. Such as short circuit protection, over current protection, exclusion control, undervoltage protection.
- Q: What are the differences between switches and circuit breakers?
- the first isolation, and then the circuit breaker; sub-gate, the first disconnect the circuit breaker, and then disconnect the isolation switch.
- Q: What is the choice of low voltage electrical circuit breaker?
- For example, a circuit breaker located outside the cockpit is temperature compensated so that its trip characteristics do not change with the temperature fluctuations common in flight.
- Q: How to look at the circuit breaker capacity is how much?
- but the circuit is not broken, must be arc to completely disconnect the circuit current, so the circuit breaker circuit is completely broken circuit called shut-off.
- 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: Leakage protector and open selection
- The third is not overloaded. Short-circuit protection function. Not directly split circuit, only leakage alarm RCD
