KLPC500 - 500Amp Fuse

KLPC500 - 500Amp Fuse

When your circuit calls for a 500A Class L time-delay fuse, the KLPC500 combines high interrupting capability, current-limiting performance, and a construction built for demanding overcurrent-protection requirements. The KLPC500 is part of the KLPC POWR-PRO series. It is rated at 500 amps and 600 volts, with a time-delay characteristic that the manufacturer says helps the fuse ride through system surges rather than opening unnecessarily. For replacement or equipment-matching work, don't stop at the 500A marking—confirm the Class L requirement, 600V rating, time-delay characteristic, interrupting requirements, and physical configuration specified for the equipment.

Key Features and Benefits

• 500A current rating for circuits and equipment specifically designed around a 500-amp Class L fuse.
• 600V rating as identified in the manufacturer's KLPC500 description.
• Class L fuse configuration provides an important compatibility point when matching an existing fuse or equipment specification.
• Time-delay performance helps the fuse withstand system surges and can reduce unnecessary circuit interruptions.
• The manufacturer specifies a minimum 10-second time delay at 500% of rated current for the KLPC series.
• The current-limiting design helps reduce equipment and system damage during short circuits.
• Designed to coordinate with other system protective components, according to the manufacturer's supplied product information.

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 ten-second time delay at 500% of rated current while maintaining current-limiting performance. The supplied KLPC500 information does not include an individual UL listing number for this specific catalog number, so none is assumed here.

Where It Works Best

The KLPC500 suits electrical equipment that requires a 500A, 600V, Class L time-delay, current-limiting fuse. The manufacturer positions the broader KLPC POWR-PRO family for overcurrent protection of circuits ranging from 200 through 6000 amps, and specifically highlights the series' ability to withstand system surges while providing current limitation during short-circuit conditions.
