Q:Is there a sequence of circuit breakers and disconnectors?
At the time of power transmission, because the circuit breaker and the disconnector are in the disconnected state, there is no current in the circuit when the switch is disconnected first,
Q:What is the solution of the leakage circuit breaker always jumping?
if it exceeds its rated current or leakage, primarily for home or office lighting and to ensure the safety of the person.
Q:What are the differences between switches and circuit breakers?
the first isolation, and then the circuit breaker; sub-gate, the first disconnect the circuit breaker, and then disconnect the isolation switch.
Q:Why the first break circuit breaker, after the isolation switch off it?
can not disconnect the charged circuit, so the disconnector should be used in conjunction with the circuit breaker.
Q:Discussion on the Selection of Circuit Breaker in Low Voltage Circuit
and the frame circuit breaker rated current is much larger, generally 630A-6300A (such as our company's DW15, DW16 and DW17 series
Q:How to look at the circuit breaker capacity is how much?
The rated breaking current of the circuit breaker is three times the root number of the product of the rated voltage, that is, the blocking capacity.
Q:Is the isolator and circuit breaker able to switch to each other?
Can he just provide a clear breakpoint now has a clear breakpoint of the breakout in our "construction site temporary electricity safety technical specifications" which referred to
Q:What circuit symbols are used for circuit breakers
that is, by the internal cycle of the protection and algebra and (including the neutral current neutral current instantaneous three-phase
Q:What is the difference between a circuit breaker and other switches?
All parts of the frame breaker are housed in an insulated metal frame, often open, can be equipped with a variety of accessories
Q:Short trip also tripped, overload also trip it?
The element combination is mainly used for short circuit and overload protection. Generally divided into 1P 1P plus N open air or. 3P or 4P, etc.
