Fuses
3.6/7.2kV Current Limiting Fuses
Features
High-voltage current limiting fuse is used alongside other protective equipment in order to protect high-voltage circuits and equipment from high-voltage over current or short circuit current, as it is highly protective and economic.
The company is manufacturing 1~200Amp standard fuses in 3.6kV/7.2kV ratings according to KSC 4612-1985 (high-voltage current limiting fuse) standards, which can be used safely in high voltage distribution board, etc.
◆ Restriction of fault current through effective current limiting effect in times of extreme over current
◆ High-speed interruption possible by minimizing through current
◆ Its structure does not have mechanical/thermal effects on system circuit or high-voltage equipment
◆ Is light and small and can be applied to a variety of purposes
- Smallest and lightest
- Has a wide range of interrupting abilities
- Reasonable price
