KLPC1900 - 1900Amp Fuse

KLPC1900 - 1900Amp Fuse

When your equipment calls for a 1900A Class L fuse, getting the amperage right is only the beginning. The KLPC1900 is a 1900A time-delay, current-limiting fuse in the KLPC POWR-PRO series, rated for systems up to 600VAC or 480VDC and built in a bolt-in configuration. For replacement or equipment matching, evaluate the KLPC1900 by its complete electrical and physical specifications—including fuse class, voltage, interrupting capability, opening characteristic, and mounting—not simply its 1900A rating.

Key Features and Benefits

• 1900A continuous current rating for equipment designed around this specific Class L rating.
• Class L configuration provides the electrical and physical format required by compatible equipment.
• Time-delay operation with a manufacturer-specified minimum delay of 10 seconds at 500% of rated current for the KLPC series.
• Current-limiting design is a defined performance characteristic of KLPC POWR-PRO fuses.
• Rated for operation in compatible systems up to 600VAC.
• Also rated up to 480VDC, giving the KLPC1900 defined AC and DC voltage capabilities.
• Bolt-in mounting provides a clearly defined installation format for compatible equipment.
• Consider the non-indicating design when matching an existing fuse or equipment specification.

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. The supplied information does not provide an individual UL listing number for KLPC1900, so do not assume a separate listing number.

Where It Works Best

The KLPC1900 1900A fuse suits electrical equipment designed for a 1900A Class L, time-delay, current-limiting fuse with bolt-in mounting. The manufacturer positions the broader KLPC series for overcurrent protection on circuits ranging from 200 through 6000 amperes, placing the KLPC1900 within that specified series range.
