KLPC800 - 800Amp Fuse

KLPC800 - 800Amp Fuse

For equipment that requires an 800A Class L fuse, the KLPC800 combines a high continuous-current rating, time-delay operation, current-limiting performance, and bolt-in construction. Rated for a maximum of 600VAC and 480VDC, this KLPC POWR-PRO fuse is designed around a clearly defined set of electrical and physical specifications, not amperage alone. If you're replacing an existing fuse, the smart approach is simple: match the 800A rating, Class L configuration, voltage, interrupting requirements, time-delay characteristic, bolt-in mounting, and non-indicating design to the equipment specifications.

Key Features and Benefits

• 800A continuous current rating for equipment designed to use an 800-amp Class L fuse.
• Class L fuse design provides a specific physical and electrical configuration for replacement matching.
• Rated for operation up to 600VAC in compatible AC equipment.
• Supports compatible DC applications up to a specified maximum of 480VDC.
• Time-delay opening characteristic helps distinguish the KLPC800 from fast-acting fuse designs.
• According to the manufacturer, KLPC series fuses provide a minimum ten-second time delay at 500% of rated current.
• Current-limiting performance is a core characteristic of the KLPC series.
• Bolt-in construction gives installers and maintenance teams another important physical characteristic to verify during replacement.
• Match the non-indicating design when replacing an existing fuse.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses and states that the series provides a minimum ten-second time delay at 500% of rated current while also delivering current-limiting performance. An individual UL listing number specifically for the KLPC800 is not included in the supplied product information, so no catalog-specific listing number is assumed here.

Where It Works Best

The KLPC800 800A Class L fuse is best suited to electrical equipment specifically designed around an 800A, time-delay, current-limiting Class L fuse with bolt-in mounting. Its defined time-delay behavior makes that characteristic especially important to match; choosing a replacement based only on the 800A marking could overlook several critical specifications.
