KLPC1800 - 1800Amp Fuse

KLPC1800 - 1800Amp Fuse

A replacement fuse has to match more than the amp number printed on the label. The KLPC1800 is a 1800A Class L time-delay, current-limiting fuse from the KLPC POWR-PRO series, rated up to 600VAC and 480VDC, with a bolt-in mounting configuration. If you're matching a KLPC1800 for existing equipment, check the complete set of requirements—1800A rating, Class L configuration, voltage, interrupting capability, time-delay characteristics, current-limiting requirements, and bolt-in mounting—not amperage alone.

Key Features and Benefits

• 1800A continuous current rating for electrical equipment designed around this Class L amperage.
• Class L fuse design provides the specific electrical and physical configuration required by compatible equipment.
• Time-delay opening characteristic allows the fuse to follow its specified time-current performance during temporary overcurrent conditions.
• The manufacturer specifies a minimum 10-second time delay at 500% of rated current for KLPC series fuses.
• Current-limiting performance is a defined characteristic of the KLPC series.
• Supports AC systems requiring a fuse rated up to 600VAC.
• Provides a 480VDC maximum rating for compatible DC equipment.
• Bolt-in mounting gives the KLPC1800 a clearly defined installation format.
• Matches 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. It also states that the series provides a minimum 10-second time delay at 500% of rated current while providing current-limiting performance.

Where It Works Best

The KLPC1800 1800A fuse suits electrical equipment designed for a Class L, 1800A, time-delay, current-limiting fuse with bolt-in mounting. The manufacturer describes the KLPC series as providing overcurrent protection for circuits from 200 through 6000 amperes, with the KLPC1800 occupying the 1800A position within that stated range.
