Q:Circuit system diagram and circuit breaker connection
Circuit breakers can not only play a role in isolation, you can protect the back of the lines and equipment
Q:Circuit breaker main circuit control power, how to wiring?
In use, the circuit breaker should be cut off the capacity of the installation should be greater than the maximum short circuit capacity
Q:Why the high-voltage circuit is equipped with isolation switch and circuit breaker
The disconnector has a clear break point, but only acts as an isolated circuit and can not be operated when the line has current. When disconnecting the circuit, be sure to disconnect the circuit breaker and disconnect the disconnector.
Q:What is the capacity of the circuit breaker
The breaking capacity of the high-voltage circuit breaker is the same as that of the rated breaking current
Q:Is 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:Does the isolator and circuit breaker able to switch to each other?
As the circuit breaker inside the arc suppression mechanism, the circuit breaker in a very short period of time (such as a few hundred seconds) will arc off, so that the circuit breaker safety separation.
Q:How to protect the leakage protector leakage protection?
Third, do not overload short circuit protection. Nor is it a direct frequency circuit, leakage alarm only the role of RCD.
Q:The specific function and operation mode of the auxiliary switch on the circuit breaker switch
High-voltage circuit breakers generally have a number of auxiliary contacts, their on-off and circuit breaker main contact the same (or vice versa), so the secondary circuit
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
