Q:What is the difference between the leakage switch and the general switch?
general configuration over-current release and instantaneous release, frame circuit breaker is functional,
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:Circuit system diagram and circuit breaker connection
Circuit breakers can not only play a role in isolation, you can protect the back of the lines and equipment
Q:How to switch from the circuit breaker switch button, the difference is short circuit protection or overload protection?
It acts as a knife switch. Fuse thermal relay and other electrical appliances
Q:The specific function and operation mode of the auxiliary switch on the circuit breaker switch
High-voltage circuit breakers generally have a number of auxiliary contacts, their on-off and circuit breaker main contact the same (or vice versa), so the secondary circuit
Q:Circuit breaker main circuit control power, how to wiring?
In use, the circuit breaker should be cut off the capacity of the installation should be greater than the maximum short circuit capacity
Q:Circuit problem! Hurry Miniature Circuit Breaker!
it may be the circuit breaker itself is faulty, need to be replaced. (Of course, there may be lines due to insulation damage and there is a short circuit, but may be smaller)
Q:What is the capacity of the circuit breaker
It is the parameter that characterizes the breaking capacity of the circuit breaker. Under the rated voltage
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:Where will the circuit breaker auxiliary contacts be used? ,
general electromagnetic molded case circuit breaker for the non-selective circuit breaker, only long delay and instantaneous two kinds of protection, electronic molded case circuit breaker has a long delay
