Q:What is the common circuit switch called switch
selection of chain functions, and fully guarantee the action of the sensitivity and selectivity.
Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
Used to control, protect, adjust, measure and monitor the parameters of the circuit and the working conditions of each component.
Q:How is the circuit breaker connected to the circuit system diagram?
Let's talk about the circuit breaker and the open circuit breaker. The following explains the difference between the disconnector and the circuit breaker.
Q:What are the differences between switches and circuit breakers?
the first isolation, and then the circuit breaker; sub-gate, the first disconnect the circuit breaker, and then disconnect the isolation switch.
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:How is the total switch breaker in the distribution box correctly
less than the leakage protection device operating current value, so leakage protection does not work. When a fault occurs
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:How to protect the leakage protector leakage protection?
can be divided into high sensitivity. Sensitivity and low sensitivity. Its working principle is my + I = nine = 0
Q:How is the circuit breaker different from the air circuit breaker?
Upstairs said the air switch is a kind of circuit breaker. The switch is a switch that can turn on and off the load current; the disconnector is an electrical device that isolates the power supply and can not turn on and off the current (except for the voltage)
Q:Is there a sequence of circuit breakers and disconnectors?
If you do not follow the above procedures, power transmission, the first circuit breaker, after the isolation switch, or power failure, the first pull off the switch, after pulling the circuit breaker, the isolation switch or pull off the switch will produce an instant arc
