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:Circuit breaker auxiliary contact is what?
Molded case circuit breaker with plastic structure, is characterized by the circuit breaker shell, the frame made of plastic from the contact, the arc system are placed in the insulating chamber
Q:Circuit breaker main circuit control power, how to wiring?
Otherwise you should use a larger capacity circuit breaker or technical transformation, reduce the installation of short-circuit capacity. Or on the circuit breaker capacity transformation
Q:How long is the circuit breaker long delay time?
Circuit breaker (English name: circuit-breaker, circuit breaker) is able to close, carry and break the normal circuit under the conditions of the current and can be closed,
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:How to distinguish between disconnectors, circuit breakers?
Because it does not have a special arc extinguishing device, can not cut off the load current and short circuit current.
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: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:Is the isolator and circuit breaker able to switch to each other?
In addition, you can also use the disconnector to change the running wiring. Therefore, the disconnector is an indispensable device in the circuit.
Q:Short trip also tripped, overload also trip it?
second with overload and short circuit protection function ..... leakage protection RCD
