Product Description:

It is supplied with rated insulating voltage 800V and used for circuit of A.C. 50Hz, rated operating voltage AC 400V (or below), rated operating current up to 800A for infrequent changing over and starting of the motors.The products conform to IEC60947-2 standard.
Main Technical Specification
Note: 6A no thermal protection
The N-pole of four-poles breaker is sifed at the right side of the product has four types:
Type A: No current trip-lease on N pole which making all the time, not closing and opening with the other three poles.
Type B: No current trip-release on N pole which closing and opening with the other poles.
Type C: With current trip-release which closing and opening with the other three poles.
Type D: With current frip-release which making all the time not closing and opening with the other three poles.

Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
but played under omission, over flow, short circuit, grounding and other basic protection ,
Q:Selection of Circuit Breakers in Low Voltage Circuits
As the temperature increases, the thermal circuit breaker trips faster and often trips at lower current levels.
Q:How is the circuit breaker different from the air circuit breaker?
can not turn on the current, you can disconnect the short-circuit current below the current (by fuse).
Q:Circuit system diagram and circuit breaker connection
, but in the maintenance can manually disconnect the circuit to ensure that maintenance personnel personal safety
Q:How to switch from the circuit breaker switch button, the difference is short circuit protection or overload protection?
Circuit Breaker Circuit Breaker. Leakage protector leakage protection is the effect of two different products is different. In any case, I seriously bored at home to reply to your question, hope to help you!
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 role of the circuit breaker?
the circuit breaker internal trip mechanism, there is a different coefficient of expansion when the two kinds of metal bonding bimetallic together,
Q:What is the common circuit switch called switch
Circuit breaker with long delay, short delay, instantaneous and ground fault four protection, each protection set value according to its frame level within a certain range of adjustment.
Q:What is the solution of the leakage circuit breaker always jumping?
Usually the concept: generally in the meter outlet outlet air switch is better, because the line distance is relatively far, if the leakage switch failure rate is relatively increased
Q:What are the differences between switches and circuit breakers?
And because of its arc extinguishing device and internal structure, he can also load with the gate
