- Q:Selection of Circuit Breakers in Low Voltage Circuits
- Compared with the fuse, the thermal protector has a significant advantage
- 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:Is there a circuit breaker in the circuit
- Fuse and circuit breaker function is the same, are used in electrical equipment in the event of overload and short circuit and other failures play a protective role
- Q:Circuit problem! Hurry Miniature Circuit Breaker!
- After removing the above problems, you can turn off all the electrical equipment or pull out the plug, such as the circuit breaker also jump
- 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:Home circuit breakers and how much air is open
- The air switch has an average operating life of 20000 times at rated load. In the understanding of the leakage switch,
- Q:Is the isolator and circuit breaker able to switch to each other?
- In addition, you can also use the disconnector to change the running wiring. Therefore, the disconnector is an indispensable device in the circuit.
- Q:Circuit system diagram how the circuit breaker said
- Most of the power applications are used in conjunction with circuit breakers and disconnectors, with the circuit breaker, load (fault) current, with the isolation switch to form a clear point
- 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:What is the specific function of the auxiliary switch on the circuit breaker switch?
- By the secondary equipment connected to each other, constitute a primary equipment for monitoring,
