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:Is the isolator switchable with a circuit breaker?
- Disconnector: similar to the knife switch, no to prevent overcurrent, short circuit function, no arc device;
- 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: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:Selection of Circuit Breakers in Low Voltage Circuits
- Compared with the fuse, the thermal protector has a significant advantage
- Q:Is the isolator and circuit breaker able to switch to each other?
- such as the use of broken break with a visible breaking point of the circuit breaker, may not be isolated Switch "disconnector can be replaced by a short circuit (technical information can be accessed)
- 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:Where will the circuit breaker auxiliary contacts be used? ,
- Most molded case circuit breakers are operated manually and partly with motor operation.
- Q:Circuit system diagram how the circuit breaker said
- the current does not exceed 5A of the no-load lines, in order to use the isolation switch for direct operation.
- 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:Home circuit breakers and how much air is open
- According to the requirements of customers and decoration personality differences, combined with the actual situation of flexible distribution plan.
