Product Introduction  

ZW32-24 outdoor high voltage vacuum circuit breakershort 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 currentoverload 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 volumelight weightanti air condensationfree maintenance etc; it can work in bad weather and pollution environment.

Q:The difference between the leakage switch of the air switch circuit breaker
Mainly used for short circuit and overload protection. General 1P1P plus N or 2P. 3P or 4P, etc.
Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
but played under omission, over flow, short circuit, grounding and other basic protection ,
Q:What is the difference between the leakage switch and the general switch?
intelligent controller and drawer seat and so on. Each part has become a complete independent components, assembly only 1-2
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:Leakage protector and open selection
Also known as leakage relay. Generally used for non-power important places
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 breaker generally choose what ah?
so RCD can cut very sensitive ground fault protection circuit can also be directly Use contact with backup shock protection.
Q:How long is the circuit breaker long delay time?
istribution circuit breaker and control circuit of the circuit breaker long delay function is different, household circuit breakers and industrial circuit breakers are different,
Q:Leakage circuit breaker old jump how to do
so do not use the earth switch to do the main switch, the proposed general switch with the general air switch ... ...
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).
