Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
Circuit breaker, it can be on the line voltage, current and other parameters to monitor, alarm, action, not only as a break poin
Q:Is the zero line going through the circuit breaker?
Three-phase four-wire zero line is absolutely not allowed to go through the circuit breaker, because the zero line is broken, the line of all 220V appliances will withstand 380V line voltage and burned.
Q:How to choose the home of the circuit breaker air switch?
air conditioning circuit, separate wiring, when one of the circuit (such as the socket circuit) failure, the other circuit can still be normal power supply.
Q:Selection of Circuit Breakers in Low Voltage Circuits
The thermal circuit breaker uses a bimetallic plate in series with the circuit. The heat generated by the current during the overload causes the bimetal to deform, causing the circuit breaker to trip
Q:Circuit system diagram how the circuit breaker said
so as to avoid serious equipment and personal accidents. Only the voltage transformer, arrester, the excitation current does not exceed 2A no-load transformer
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:Does the isolator and circuit breaker able to switch to each other?
When the circuit breaker disconnect the live circuit, the internal contact in the separation of the moment will produce an arc, the higher the voltage or the greater the current, the stronger the arc.
Q:Isolation switch, circuit breaker, open the three What is the difference between ah
Circuit Breakers High-voltage circuit breakers, and low-voltage circuit breakers are an electrical protection device, and its type is very much with an arc extinguishing device
Q:What type of switch circuit breaker has undervoltage protection
In addition it is best to put the lighting circuit, high-power electrical circuit, such as a separate circuit breaker
Q:Home no electricity corridor switch the total switch circuit burned how the matter
here are two general reasons, one is the switch quality is not good, the second is the existence of the installation quality defects
