Product Description:


Hydraulic magnetic mini circuit breaker is mainly suitable for overload and short circuit protection. It adopts 

hydraulic magnetic trip instead of bimetal. So it has a high sensitivity and the ambient temperature does also 

not affect it. It is especially used for illumination and distribution in industry and commerce. 

They are mainly used for overload and short circuit protection within the circuit of AC 50/60Hz, rated voltage of single 

pole or double poles up to 240V, three poles up to 415V. They can also be used for an unfrequented switchover 

of the circuit and illumination under normal conditions. 



They comply with IEC 157-1973 BC4752-1977 and BS 3871 PART 1.

Q:What is the difference between the breaking capacity of the fuse and the fusing capacity
Such as the US standard (UL248-1 & 14) 2 times the rated current overload test, requiring the fuse in 60 seconds fuse
Q:Is the fuse blown directly with copper wire?
While the melting point of copper wire is much higher than the lead tin, the current is still not large when the fuse will damage the electrical. If you can not find it,
Q:Is the fuse blown depending on the size of the current flowing through it?
This shows that the fuse can only be placed in the operating voltage is less than or equal to the rated voltage fuse circuit.
Q:What is the role of thermal fuse
Mainly to protect the electrical equipment due to overheating and burn electrical appliances, such as the motor is the use of thermal protection to protect the motor.
Q:When replacing the melt, it is required to
Before installing the new melt, find out the cause of the melt fuse, not determine the cause of the fuse, do not replace the melt test.
Q:Quickly disconnect the fuse and cut off the fuse slowly
Slow-breaking fuses remain intact when there is a non-faulty pulse current (such as a pulse generated by a switch), and a long-term current overload is protected, and there is no such function
Q:What is the significance of the voltage on the fuse?
imilar to the neon bulb principle. Will make short circuit has a current through, to expand the fault. The The But also cause danger.
Q:The air switch is different from the fuse
For line protection cut off and power on.
Q:How to read the fuse ring
four color ring followed by: red, red, yellow, gold. The first color ring red for 2, the second color ring red 2, are valid numbers, the third color ring yellow is 4, said the effective number after 4 "0", the fourth ring is golden, that the error is 5%
Q:What are the fuse, automatic repair fuse what principle
Fuses for overtemperature protection are commonly referred to as temperature fuses.
