The all new LLSRK_ID series fuse is the most advanced Class RK1 fuse available today providing unparalleled performance and protection to modern circuits. The patented Indicator™ technology provides instant identification of a blown fuse greatly enhancing system up time, while the precision formed short circuit elements virtually eliminate damage to components from unexpected electrical faults. In addition, the all new solid-state overload section has no moving parts, stopping unnecessary fatigue failures commonly found in other spring loaded fuses.
- Applications
- Features
| All general purpose circuits |
| Time-Delay |
| POWR-PRO™ performance |
| IEC Type 2 "no damage" protection to IEC and NEMA type motor starters |
| This robust design withstands repeated surges within rated time delay without opening needlessly, eliminating downtime caused by power surges or equipment demands |
| Reduce down time the indicating window of the LLSRK_ID immediately identifies the open fuse, if the window is dark, the fuse has opened, It's that simple, maintenance personnel can immediately determine that there is an open fuse |
| Reduce fuse inventory the superior performance of the LLSRK_ID allows it to be used in a variety of applications, thus decreasing fuse inventory |
| Reduce nuisance opening - indicator fuses offer superior time delay and cycling characteristics, which can lengthen fuse life |
| 200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating |
