KLPC450 - 450Amp Fuse

KLPC450 - 450Amp Fuse

The KLPC450 is a 450A Class L time-delay, current-limiting fuse for your electrical equipment that requires the specific ratings and bolt-in configuration of the KLPC series. Rated up to 600VAC and 480VDC, this POWR-PRO fuse combines a time-delay opening characteristic with current-limiting performance. For a replacement, don't stop after matching the 450A marking. Confirm the Class L requirement, AC or DC voltage, interrupting rating, time-delay characteristic, bolt-in format, and non-indicating design against the equipment specifications.

Key Features and Benefits

• 450A continuous current rating for equipment designed around this specific Class L fuse rating.
• Class L configuration provides a key reference point when checking replacement compatibility.
• Rated for a maximum of 600VAC.
• Also rated up to 480VDC for compatible DC equipment.
• The manufacturer identifies time-delay operation as Slo-Blo / Time Lag (T) / Time Delay.
• According to the manufacturer, KLPC series fuses provide a minimum 10-second time delay at 500% of rated current.
• Current-limiting design is a stated characteristic of the KLPC series.
• Bolt-in construction and mounting give maintenance teams a clear physical characteristic to check against the existing installation.
• Confirm 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 and states that the series provides a minimum 10-second time delay at 500% of rated current while maintaining current-limiting performance.

Where It Works Best

The KLPC450 suits electrical equipment that requires a 450A Class L time-delay, current-limiting fuse in a bolt-in configuration. The manufacturer places the broader KLPC series within its fuse range for circuits from 200A through 6000A, with the KLPC450 providing the 450A rating covered here.

For AC service, check the equipment specification against the 600VAC maximum rating and the applicable supplied AC interrupting value. For DC service, verify the 480VDC maximum rating and 20,000A interrupting rating at 480VDC. Physical compatibility matters too, so confirm the Class L format and bolt-in mounting arrangement.
