300-AMP 600-VOLT FAST ACTING CLASS-J FUSE - LITJLS300>
Description
300-AMP 600-VOLT FAST ACTING CLASS-J FUSE
- Applications:
- General purpose circuits with little or no motor load.
- Resistive loads, such as resistance electric heat.
- Loads requiring fast-acting overload protection, such as equipment containing solid-state devices.
- Space Saving:
- JLS fuse characteristics are similar to KLNR/KLSR fast-acting Class RK1, but they are much smaller.
- Safety:
- 200,000 A.I.R. — Reliable interruption of all overcurrents up to 200,000 amperes.
- Extremely current limiting — Stops damaging short-circuit current faster than any mechanical protective device.
- Fast-Acting — Provides fast-acting protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components.
- Longer Equipment Life:
- Current-limiting design reduces damage to equipment caused by heating and magnetic effects of short-circuit currents.
- Economical:
- Extremely current-limiting design often permits use of readily available, less costly equipment.
- Manufacturers of equipment containing dual voltage devices can simply manufacturing and reduce inventory by standardizing on 600 volt JLS fuses and Class J fuse blocks for all AC voltage ratings.
- Easy to Use:
- 200,000 A.I.R. rating minimizes need for short-circuit calculations.
