- Q: Frame circuit breaker, molded case circuit breaker difference
- but many people are not very aware of the differences between the two, in the purchase time often appear indecisive situation.
- Q: Leakage circuit breaker is not on, how to do
- Disconnect all electrical appliances from the line; Adjust the switch of all the lamps to the open position; (the lamp is not energized)
- 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 to choose a circuit breaker for home and small office circuits
- The test button should be tested once a month to check the function of the leakage connector.
- 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,
- 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: Leakage protector and open selection
- and to release the power off the release device according to its breaking reaction time can be divided into high sensitivity
- Q: What is the length of time that the circuit breaker can delay?
- his curve is plotted for multiple circuit breakers under different trip currents at different trip times. In recent years,
- Q: The difference between air switch and circuit breaker
- The air switch is our usual familiar name, it is the correct name called air circuit breaker. Air circuit breakers are generally low pressure, that is rated operating voltage of 1Kv
- 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
