Q:Selection of Circuit Breakers in Low Voltage Circuits
The thermal circuit breaker uses a bimetallic plate in series with the circuit. The heat generated by the current during the overload causes the bimetal to deform, causing the circuit breaker to trip
Q:Is there a sequence of circuit breakers and disconnectors?
The disconnector does not have an arc extinguishing mechanism that can cause equipment damage and personal injury and death, and cause a large area power outage.
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:Circuit breaker auxiliary contact is what?
Molded case circuit breaker with plastic structure, is characterized by the circuit breaker shell, the frame made of plastic from the contact, the arc system are placed in the insulating chamber
Q:Home circuit breakers and how much air is open
According to the requirements of customers and decoration personality differences, combined with the actual situation of flexible distribution plan.
Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
You said the knife can be understood as a kind of isolation switch, it is only as a circuit break point, no lines, load protection function
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:The difference between air switch and circuit breaker
Such as short circuit protection, over current protection, exclusion control, undervoltage protection. The first two kinds of protection for the basic configuration of the air circuit breaker, the latter two for the optional function
Q:Leakage circuit breaker is not on, how to do
If you close one of the shunt switch, if the trip or not when the gate, indicating that the road is short circuit or leakage.
Q:What is the specific function of the auxiliary switch on the circuit breaker switch?
control, regulation and protection of the electrical circuit known as the secondary circuit. Is in the electrical system by the transformer secondary winding,
Our company integrates research, development, manufacture and sale, and is specialized in the production of various the low-voltage electrical industry.Our company uses scientific management methods, cultivates and develops a number of professional talents in technological and business management and presents a development pattern of productive specialization, brand diversification, specification serialization and scientific management.
