RK1 fuses are extremely current-limiting fuses meaning they greatly reduce or eliminate damage to circuits and equipment under short circuit conditions. Replacing existing Class H, K and RK5 fuses with RK1 fuses is one of the easiest ways to immediately improve the protection of plant workers and equipment.
- Applications
- Features
| All general purpose circuits |
| Time-Delay |
| Extremely current limiting - reduces damage to circuits and equipment under short circuit conditions |
| Stops damaging short circuits faster than any mechanical protective device |
| Reduced costs - current limiting design often permits use of readily available, less costly equipment |
| Low resistance design reduces power consumption and utility bills |
| Excellent time delay - true dual element construction, with separate non-fatiguing thermally-reversible spring loaded thermal overload element, withstands repeated surges within rated time delay without opening needlessly |
| Eliminates needless downtime caused by power surges or equipment demands |
| 200 kA at 250 VAC, 20 kA at 125 VDC interrupting rating |
