company news about Fuse holder test method

1. Temperature and voltage test: Use the power supply to apply voltage and current on the fuse. The fixed voltage is 220 volts, and the current is supplied from 2 ampel. The temperature increases at the temperature of 2 ampel to 10 ampere current every 4-5 minutes.

2. Follow time test: Use a stopwatch to record observation 2 times the rated current and the remaining current values. The measurement required for measuring the melting. situation.

3. fuse sample test: Among them, whether it is 2 times the rated current or the supply of other current values, the three same specifications of fuse samples are experimented to an average melting time.
