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 the isolator switchable with a circuit breaker?
Disconnector: similar to the knife switch, no to prevent overcurrent, short circuit function, no arc device;
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 breaker main circuit control power, how to wiring?
he blocking capacity is equal to the breaking current (the manual specifies the rated breaking current of the high voltage electrical appliance
Q:What is the solution of the leakage circuit breaker always jumping?
Usually the concept: generally in the meter outlet outlet air switch is better, because the line distance is relatively far, if the leakage switch failure rate is relatively increased
Q:Which is the circuit switch, that is the circuit breaker
sub-capacity and so are greater than Molded Case circuit breaker. This is a fundamental difference,
Q:Is the zero line going through the circuit breaker?
Three-phase three-wire, the use of protection to zero system, the zero line is absolutely not allowed to go through the circuit breaker, because the zero line is broken,
Q:Is the circuit breaker in the circuit necessary?
when the current is slightly larger, will only cut off the other two phase to produce too much electric current Arched open
Q:Is it possible to switch the lamp directly with a circuit breaker?
Circuit breaker according to its use is divided into high-voltage circuit breakers and low-voltage circuit breakers, high and low voltage line is more vague, generally more than 3kV called high-voltage electrical appliances.
Q:How long does the circuit breaker last?
the introduction of intelligent circuit breaker long delay trip is based on the formula to simulate the mechanical circuit breaker trip curve, each company calculation method is different, and is the company's core secrets.
