Q:Circuit system diagram and circuit breaker connection
, but in the maintenance can manually disconnect the circuit to ensure that maintenance personnel personal safety
Q:Leakage protector and open selection
The principle of the use of RCD zero sequence current transformer To detect leakage, electric shock and other ground fault current
Q:What are the differences between switches and circuit breakers?
Generally in the power supply system, the isolation in the upper part of the circuit breaker, so the order of operation: closing
Q:Selection of Circuit Breakers in Low Voltage Circuits
Compared with the fuse, the thermal protector has a significant advantage
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:How long is the circuit breaker long delay time?
within the specified time to carry and break the abnormal circuit under the conditions of the current
Q:Leakage circuit breaker old jump how to do
Leakage protection The main role is to solve the leakage problem: how much current out of the phase line, the neutral line will come back how much current
Q:Is the isolator and circuit breaker able to switch to each other?
when the equipment or line is overhauled to ensure safety. In addition, you can also use the disconnector to change the running wiring.
Q:What is the difference between a circuit breaker and other switches?
All parts of the frame breaker are housed in an insulated metal frame, often open, can be equipped with a variety of accessories
Q:What is the role of the circuit breaker?
the circuit breaker internal trip mechanism, there is a different coefficient of expansion when the two kinds of metal bonding bimetallic together,
