KLLU series UL Listed, time-delay, Class L are quality fuses in every sense of the word. They were developed to provide a somewhat lower priced alternate to the POWR-PRO KLPC series fuses. KLLU series fuses meet or exceed all UL requirements for Class L fuses. For superior protection and performance, specification-grade POWR-PRO KLPC series fuses are the recommended fuses.
- Applications
- Features
| Service Switches/Switchboard Mains |
| Time-Delay |
| Current limiting - reduces short circuit damage to systems and equipment and reduced downtime |
| Easily coordinated with other system components |
| Ten second minimum time delay at 500 percent of rating eliminates needless downtime caused by heavy starting currents of large motors and other inductive loads |
| Selective coordination - KLLU fuses coordinate well with other class L fuses and with all current-limiting Littelfuse® fuses rated 600 A or less |
| Reduced downtime |
| KLLU fuse time-current characteristics closely match typical time-current curves of circuit breakers |
| Although fuse/circuit breaker systems can seldom be 100 percent coordinated , KLLU series fuses permit use of a wider range of breaker setting than fast-acting class L fuses |
| Excellent protection for a single breaker or a group of breakers |
| 200 kA at 600 VAC, 20 kA at 300 VDC interrupting rating |
