Q:Is the circuit breaker in the circuit necessary?
When the air is open, it is not recommended to use the fuse, need to protect, open the three-phase at the same time off, such as with the fuse
Q:What is the difference between the leakage switch and the general switch?
screws can be fixed, easy disassembly is conducive to maintenance maintenance.
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:Is there a circuit breaker in the circuit
Such as the circuit breaker at work, when a failure occurs, it is the power of all disconnected.
Q:Leakage circuit breaker is not on, how to do
Close the total circuit switch; (line power state) Then separate the shunt switch one by one
Q:What is the length of time that the circuit breaker can delay?
do not know what kind of circuit breaker you said. Long delay function in general is a trip time and overload current into inverse time relationship
Q:Load switch, vacuum switch and circuit breaker
Load switch: can safely cut off the load current, can not cut off the short circuit current
Q:Isolation switch, circuit breaker, open the three What is the difference between ah
Isolated switch is a high voltage switchgear mainly used in high voltage circuit
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:Where will the circuit breaker auxiliary contacts be used? ,
short delay, Instantaneous and ground fault four protection functions. Part of the electronic molded case circuit breaker new products also have a regional selective chain function
