KLPC3000 - 3000Amp Fuse

KLPC3000 - 3000Amp Fuse

The KLPC3000 is a 3000A Class L time-delay, current-limiting fuse for high-amperage electrical equipment that requires a bolt-in fuse construction. Rated for up to 600VAC and 480VDC, it combines a substantial current rating with the defined operating characteristics of the KLPC POWR-PRO series. If you're matching a KLPC3000 for an existing installation, don't stop at the 3000A rating. Fuse class, AC or DC voltage, interrupting requirements, time-delay characteristics, and bolt-in configuration must match the equipment specification.

Key Features and Benefits

• 3000A continuous current rating for electrical equipment specifically designed around this Class L fuse rating.
• Rated for a maximum of 600VAC, giving the KLPC3000 a clearly defined AC operating limit.
• It is also rated for up to 480VDC in compatible DC equipment.
• The Class L fuse configuration is an important compatibility point when evaluating a replacement.
• The time-delay opening characteristic helps distinguish the KLPC3000 from fast-acting fuse designs.
• The KLPC series provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer.
• Current-limiting performance is a core characteristic of the KLPC series.
• Bolt-in construction makes the physical mounting method straightforward to identify during replacement checks.
• Confirm the non-indicating design when matching the fuse to an existing installation.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses. It also states that the series combines its minimum 10-second time delay at 500% of rated current with current-limiting performance. The supplied information does not provide an individual UL listing number for the KLPC3000, so do not assume a catalog-specific listing number.

Where It Works Best

The KLPC3000 3000A Class L fuse suits electrical equipment that requires a 3000A, time-delay, current-limiting Class L fuse with bolt-in mounting. The manufacturer positions the broader KLPC series for overcurrent protection in circuits from 200 through 6000 amperes, with the KLPC3000 providing the specific 3000A configuration described here.

For AC service, confirm the equipment meets the 3000A continuous current rating, 600VAC maximum voltage, applicable AC interrupting rating, Class L configuration, time-delay characteristic, and bolt-in mounting. For DC service, verify compatibility with the 480VDC maximum voltage and 20,000A interrupting rating at 480VDC.
