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:Which is the circuit switch, that is the circuit breaker
Simply said the size of the difference, not only the size of the frame circuit breaker to be larger than the molded case circuit breaker, and the frame circuit breaker current level,
Q:Circuit breaker generally choose what ah?
To this end, set the value of RCD, that is, its current I △ n movement, just to escape the normal amount of leakage current value, the value of milliamperes,
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:Is the isolator and circuit breaker able to switch to each other?
when the equipment or line is overhauled to ensure safety. In addition, you can also use the disconnector to change the running wiring.
Q:How to switch from the circuit breaker switch button, the difference is short circuit protection or overload protection?
The circuit breaker is called open SPACE> This is a switch that can automatically protect the low voltage distribution
Q:How is the total switch breaker in the distribution box correctly
such as leakage or physical impact is achieved through the sensing element to its leakage or electric shock leakage
Q:What is the role of the circuit breaker?
Circuit breaker in the line when the current can be disconnected from the power supply, the protection of the line, the principle is as follows
Q:Low-voltage circuit breaker is what can be broken and under normal conditions of the circuit
Low-voltage circuit breaker is able to connect, carry and break the normal circuit under the conditions of the current switch
Q:Where will the circuit breaker auxiliary contacts be used? ,
generally do not consider maintenance, suitable for branch protection switch, over current release There are two kinds of electromagnetic and electronic
