Q:How to choose the home of the circuit breaker air switch?
Actually refers to the circuit breaker with leakage protection device, the role is when the leakage current exceeds 30 mA, the leakage of accessories automatically trip to protect the human body safety
Q:Load switch, vacuum switch and circuit breaker
Load switch: can safely cut off the load current, can not cut off the short circuit current
Q:How is the total switch breaker in the distribution box correctly
less than the leakage protection device operating current value, so leakage protection does not work. When a fault occurs
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:How to protect the leakage protector leakage protection?
Third, do not overload short circuit protection. Nor is it a direct frequency circuit, leakage alarm only the role of RCD.
Q:Double control switch circuit diagram
Double control switch refers to a device for two separate control, such as if it is lighting, that there are in the living room control the living room lighting
Q:How to choose a circuit breaker for home and small office circuits
Leakage accessory handle. Leakage causes not removed before the small circuit breaker handle and leakage accessory handle can not be reset.
Q:Household leakage circuit breakers, circuit problems
Leakage circuit breaker DZ47LEC63, electric problem. Anxious ~ ~ ~ ~ ~ reward points: 80 - from the end of the problem there are 14 days 23 hours 1
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:Discussion on the Selection of Circuit Breaker in Low Voltage Circuit
Frame circuit breakers have reached this standard). Also in the segment ability,
