- Q: he circuit breaker in the circuit mainly plays a protective element what protects the two functions of the element
- When the circuit is short-circuited or the current is large, the current coil quickly pulls the armature Drive trip mechanism trip.
- Q: Household leakage circuit breakers, circuit problems
- do not know how the points. Maybe 2P, but I do not know. Four holes, up and down two, how to take this
- Q: How to protect the leakage protector leakage protection?
- Capture leakage, electric shock and other ground fault current. Trip and strokes according to its breaking reaction time cut off the power
- Q: Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
- led and so can not light The Is the base high level, N tube is generally off, low level, N tube open
- Q: What is the difference between a circuit breaker and other switches?
- In practical applications, more than 800A loop or segmentation capability requires particularly high circuit or the need for more features of the circuit should be used frame circuit breaker,
- Q: How is the circuit breaker different from the air circuit breaker?
- can not turn on the current, you can disconnect the short-circuit current below the current (by fuse).
- Q: Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
- but played under omission, over flow, short circuit, grounding and other basic protection ,
- Q: Circuit problem! Hurry Miniature Circuit Breaker!
- such as the access line loose, due to contact resistance becomes larger, will cause heat to make the circuit breaker malfunction.
- Q: Where will the circuit breaker auxiliary contacts be used? ,
- general electromagnetic molded case circuit breaker for the non-selective circuit breaker, only long delay and instantaneous two kinds of protection, electronic molded case circuit breaker has a long delay
- Q: What is the length of time that the circuit breaker can delay?
- that is to say the greater the overload the greater the tripping time, overload current tripping time is long
