Q:How long does the circuit breaker last?
functional switching appliances should be able to be suitable for the most arduous work system may have;
Q:Home circuit breakers and how much air is open
the principle of air switch, the function of the general situation for the customer matching distribution box in the process, should be in a small lighting, socket, air conditioning large matching principle
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:What is the choice of low voltage electrical circuit breaker?
n addition, due to the internal locking mechanism of the thermal circuit breaker, it is extremely insensitive to shock and vibration.
Q:What is the capacity of the circuit breaker
the maximum short-circuit current of the circuit breaker can ensure the breaking current is the rated breaking current.
Q:Is it possible to switch the lamp directly with a circuit breaker?
Circuit breakers can be used to distribute power, not frequently start the asynchronous motor, the power lines and motors and other protection, when they have a serious overload or short circuit and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch
Q:Is the circuit breaker in the circuit necessary?
occasionally short-time overcurrent motor can withstand, but the fuse blown, but also affect the production.
Q:How to distinguish between disconnectors, circuit breakers?
In the closed state can be reliably through the normal load current and short circuit fault curren
Q:Why the first break circuit breaker, after the isolation switch off it?
Power failure, the circuit there is current, because the circuit breaker has the ability to arc, the first pull circuit breaker, there will be no problem,
Q:What is the length of time that the circuit breaker can delay?
The tripping characteristic curve of the related product can be found in the corresponding relationship between the specific trip time and the overload current
