KLPC4000 - 4000Amp Fuse

KLPC4000 - 4000Amp Fuse

At 4000 amps, choosing the correct fuse means checking considerably more than the number printed on the label. The KLPC4000 is a 4000A Class L time-delay, current-limiting fuse with a bolt-in configuration, rated for up to 600VAC and 480VDC. Whether you're identifying a replacement KLPC4000 or checking compatibility for existing electrical equipment, confirm the 4000A rating, Class L configuration, voltage and interrupting requirements, time-delay characteristic, bolt-in mounting, and non-indicating design before making the match.

Key Features and Benefits

• 4000A continuous current rating for equipment specifically designed around this Class L fuse rating.
• Class L fuse configuration provides an important compatibility point for replacement and equipment verification.
• Rated for operation up to 600VAC.
• Supports compatible DC equipment with a maximum rating of 480VDC.
• Time-delay opening characteristic is specified as Slo-Blo / Time Lag (T) / Time Delay.
• The KLPC series provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer.
• Current-limiting performance is a defined characteristic of the KLPC series.
• Bolt-in construction gives technicians and buyers a clear physical mounting characteristic to verify.
• Confirm the non-indicating design when matching the KLPC4000 to existing equipment.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses and states that the series provides a minimum 10-second time delay at 500% of rated current while also providing current-limiting performance. An individual UL listing number for the KLPC4000 is not included in the supplied information, so no catalog-specific listing number is assumed.

Where It Works Best

The KLPC4000 is best suited to electrical equipment specifically designed for a 4000A Class L, time-delay, current-limiting, bolt-in fuse with the corresponding electrical requirements. The manufacturer places the KLPC family within its 200A through 6000A circuit-protection range, with the KLPC4000 providing the 4000A rating covered here.

For AC equipment, verify compatibility against the 4000A continuous current rating, 600VAC maximum voltage, applicable AC interrupting requirement, Class L configuration, time-delay characteristic, and bolt-in mounting. For DC service, check the equipment requirements against the 480VDC maximum voltage and 20,000A interrupting rating at 480VDC.
