KLPC650 - 650Amp Fuse

KLPC650 - 650Amp Fuse

The KLPC650 is a 650-amp Class L time-delay, current-limiting fuse designed for your electrical equipment that requires the specific ratings and bolt-in configuration of the KLPC POWR-PRO series. With maximum ratings of 600VAC and 480VDC, this fuse combines defined time-delay performance with high-interrupting capability. For replacement work, the 650A rating is only part of the match. Before selecting the fuse, check the Class L designation, time-delay characteristic, voltage and interrupting requirements, physical configuration, and bolt-in mounting against the equipment specifications.

Key Features and Benefits

• 650A continuous current rating for equipment specifically designed around a 650-amp Class L fuse.
• Rated for electrical systems requiring up to 600VAC.
• Supports compatible DC applications with a 480VDC maximum voltage rating.
• Time-delay opening characteristic provides a defined response to temporary overcurrent conditions.
• KLPC series performance includes a minimum ten-second time delay at 500% of rated current.
• Current-limiting design is part of the KLPC series performance specification.
• Bolt-in construction and mounting provide a specific physical format for equipment compatibility.
• Confirm the non-indicating design when matching the KLPC650 to an existing installation.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses and states that the series provides a minimum ten-second time delay at 500% of rated current while delivering its specified current-limiting performance. The supplied information does not provide an individual UL listing number specifically for KLPC650, so no catalog-specific listing number is assumed.

Where It Works Best

The KLPC650 650A Class L fuse best matches electrical equipment that requires a 650A, time-delay, current-limiting Class L fuse with bolt-in mounting. Its minimum ten-second time delay at 500% of rated current makes that operating characteristic an important part of the selection—not simply an extra specification on the data sheet.
