KLPC750 - 750Amp Fuse

KLPC750 - 750Amp Fuse

When your equipment calls for a 750A Class L fuse, amperage is only part of the match. The KLPC750 is a 750-amp, time-delay, current-limiting fuse in the KLPC POWR-PRO series, rated up to 600VAC and 480VDC, with a bolt-in mounting design. For replacement work, check the complete set of requirements—not simply the 750A rating. Fuse class, AC or DC voltage, interrupting requirements, time-delay characteristics, non-indicating design, and bolt-in configuration should match the equipment specifications.

Key Features and Benefits

• 750A continuous current rating for equipment designed around a 750-amp Class L fuse.
• Class L configuration provides a clearly defined fuse class for accurate replacement matching.
• Handles compatible AC applications with a maximum voltage rating of 600VAC.
• For compatible DC equipment, the maximum specified voltage is 480VDC.
• The time-delay opening characteristic is designed around the specified operating behavior of the KLPC series.
• The manufacturer specifies a minimum ten-second time delay at 500% of rated current for KLPC series fuses.
• Current-limiting design is a key performance characteristic of the KLPC family.
• Bolt-in construction and mounting make physical compatibility easy to identify when checking an existing installation.
• The non-indicating design means you should check the indicating status when matching the KLPC750 to an existing fuse.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses. It also states that KLPC series fuses provide a minimum ten-second time delay at 500% of rated current while maintaining the series' specified current-limiting performance. The supplied information does not provide an individual UL listing number specifically for the KLPC750, so no catalog-specific listing number is assumed.

Where It Works Best

The KLPC750 750A Class L fuse suits electrical equipment designed for a 750A, time-delay, current-limiting Class L fuse with bolt-in mounting. Its specified minimum ten-second time delay at 500% of rated current is a key operating characteristic of the KLPC series, so match it as carefully as the amperage and physical configuration.
