Applications:
L7 has protective function of overload, and is used in lighting distribution system in industry, commerce, dwelling and protect fractional electric motors. They also have many merits of high protective grade (up to IP20), high breaking capacity, reliable sensitive action, convenient multi-pole assembling and long life. They are mainly adapted to the circuit of AC 50Hz, 230V in single-pole, 400V in double/three/four-pole for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal conditions.

- Q:What are the precautions for using the fuse?
- fuse melt according to the requirements of the use of matching melt, not allowed to arbitrarily increase the melt or use other conductors instead of the melt
- Q:What does the fuse HRC say?
- It limits the fusing time at the rated voltage to be equal to or less than the first main wave or symmetrical current wave period,
- Q:What are the characteristics of the fuse?
- The rated current of the fuse should be larger than the rated current of the melt and be determined with the main electrical appliance
- 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:What is the use of the fuse?
- fuses are widely used in power grid protection and electrical equipment protection,
- Q:Fuse F5AL250V said what
- it is possible to burn the circuit or even cause a fire.
- Q:Fuses can be divided into high-voltage fuses and low-voltage fuses.
- According to the structure can be divided into open, semi-enclosed, tube and jet fuses.
- Q:Is the fuse the same as the fuse?
- Fuses by the various departments of experts and professors through research and development of a new type of high breaking capacity fuse or high pressure fuse equipment.
- Q:Where can the fuse be used?
- it is possible to burn the circuit or even cause a fire
- 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
