- Q:Why can not change the fuse when replacing the fuse
- Fuse is to limit the current to ensure that the meter does not burn
- Q:Socket and fuse are connected to the zero line or FireWire
- In other words, the fuse can only be installed on the line of fire.
- Q:What is the use of the fuse?
- when the power grid or electrical equipment occurs short-circuit fault or overload,

- In addition, the screw is not tightened when the fuse is installed, or fuse damage can also cause fuse blown.
- Q:Fuses can be divided into high-voltage fuses and low-voltage fuses.
- the protection of the voltage transformer fuse, the protection of the power capacitor fuses, protect the semiconductor components of the fuse,
- Q:How to read the fuse ring
- but it is the first, second and third ring for the effective value, the fourth ring is a valid number after the number of "0", the fifth color ring number that error: 1% in brown, red for 2%, 0.5% green, 0.25% blue, 0.1% purple
- Q:What is the melt of the fuse?
- The melt current is typically one to two times the rated current.
- Q:What is the role of the circuit breaker
