Q:Circuit breaker and fuse in the role of what in common

when they have a serious overload or short circuit and undervoltage failure can automatically cut off the circuit, its function is equivalent to the fuse switch

Q:Socket and fuse are connected to the zero line or FireWire

it will blow, cut off the power to protect the entire circuit safety, so the provisions of the fuse (or fuse) can only be installed On the line of fire, and the zero line is not allowed to install,

Q:Why can not the neutral line fuse

And when the zero line fuse blown after the shell is only in the ground insulation is not good

Q:What is the best material for electric brake fuses?

Fuse material is mainly made of low-melting alloy such as aluminum antimony alloy. Is to achieve the purpose of lower melting points added.

Q:Fuse fuse all the reasons

Fuse blown the essence: the current flows through the fuse heat, so that the fuse heat, if the heat can not be dispersed in time, the fuse continues to heat up to melt melting after the break.

Q:What is a closed fuse:

Fill the fuse with a general square tube, built-in quartz sand and melt, breaking capacity,

Q:How does the fuse be classified

According to the rated voltage points, can be divided into: high-voltage fuses, low-voltage fuses and safety voltage fuses.

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:Fuse inspection check how to do?

fuse fuse signal is normal.

Q:Fuse blown current and time

Fuse fuse is due to the current work to produce heat to achieve the fuse fuse point and fuse for circuit protection in the circuit P = I * I * R,
