Q:What is the capacity of the circuit breaker
The breaking capacity of the high-voltage circuit breaker is the same as that of the rated breaking current
Q:What is the role of the circuit breaker?
High and low voltage switchgear, to the whole product using digital transmission security monitoring, appearance modeling, performance indicators, durability to the country, and industry standards, praised by domestic and foreign customers.
Q:What type of switch circuit breaker has undervoltage protection
For example: Model DZ10-100 / 330 circuit breaker with over voltage, undervoltage protection function, from its model in the symbol / behind the second 3
Q:Why the high-voltage circuit is equipped with isolation switch and circuit breaker
The circuit breaker has an overload protection function that can operate with current. But the contact is covered by the arc extinguishing device, the break point is not visible.
Q:Is the isolator switchable with a circuit breaker?
Circuit breaker: with overcurrent, short circuit automatic trip function, with degaussing arc extinguishing device, can be used to connect, cut off the high current;
Q:Is this an air switch or a leak protector?
The working principle is simple to say that any electrical appliances will be hot at work and the degree of heat and power into Proportional.
Q:Circuit problem! Hurry Miniature Circuit Breaker!
Circuit breaker trip and leakage instructions do not pop up, indicating that the leakage is not a jump or jump
Q:What circuit symbols are used for circuit breakers
Residual current protection device (hereinafter referred to as the NLD), which detects the residual current,
Q:Circuit breaker auxiliary contact is what?
and the need to pay attention to the place. Frame breaker has high capacity and function - engineer 1
Q:Circuit breaker generally choose what ah?
so RCD can cut very sensitive ground fault protection circuit can also be directly Use contact with backup shock protection.
