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 fuses and fuses?
Fuse is the fuse, the fuse is commonly known as the fuse is the standard call.
Q:The difference between the fuse and the air switch
The air switch disconnects all of the power supply from the faulty circuit
Q:Fuse F5AL250V said what
when the fuse itself cut off the current, so as to protect the safe operation of the circuit.
Q:Why the resistance of the fuse to be large
The size of the current and the resistance determines the rate at which the heat is generated. The structure of the fuse and the condition of its installation determine the rate of heat dissipation. If the velocity of heat is less than the rate of heat dissipation, the fuse will not blow
Q:Is the home fuse fine fine or thick?
Rice cookers, cookers, water heaters that electricity is relatively large. Although it can not be used at the same time
Q:Why can not change the fuse when replacing the fuse
the resistance becomes smaller, in the case of a larger current May not burn, so that the role of the protection of electrical appliances
Q:Fuse blown current and time
and W = PT which can be seen from the fuse fuse current and time relationship.
Q:According to the breaking speed, can be divided into
Special fast fuse (generally indicated by FF)
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:Are there any resistance to the fuse?
In general, when the circuit current or voltage exceeds the rated value, the fuse will not immediately fuse
