Q:Circuit breaker generally choose what ah?
In the case of low voltage leakage protection grid installation, under normal circumstances, the grid line to ground leakage current (for three-phase power grid unbalanced leakage
Q:What is the difference between open air and circuit breakers?
The first two kinds of protection for the basic configuration of the air circuit breaker, the latter two for the optional function. So the air circuit breaker can also fault in the state (load short circuit, load over current, low voltage, etc.) cut off the electrical circuit
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: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,
Q:What is the choice of low voltage electrical circuit breaker?
At present, some high-performance circuit protection devices provide circuit breakers specifically designed for extreme shock and vibration environments.
Q:Load switch, vacuum switch and circuit breaker
Circuit breaker: not only can be cut off and connected to the load current can also cut off the fault current, such as short circuit current
Q:he circuit breaker in the circuit mainly plays a protective element what protects the two functions of the element
the thermal element drives the tripping mechanism for a certain period of time.
Q:What are the differences between switches and circuit breakers?
Generally in the power supply system, the isolation in the upper part of the circuit breaker, so the order of operation: closing
Q:How long is the circuit breaker long delay time?
Switchgear. Circuit breaker according to its use is divided into high-voltage circuit breakers and low-voltage circuit breakers, high and low voltage line is more vague, generally more than 3kV called high-voltage electrical appliances.
Q:Circuit system diagram how the circuit breaker said
so as to avoid serious equipment and personal accidents. Only the voltage transformer, arrester, the excitation current does not exceed 2A no-load transformer
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.
