KLPC600 - 600Amp Fuse

KLPC600 - 600Amp Fuse

The KLPC600 is a 600A Class L time-delay, current-limiting fuse for your electrical equipment that requires high interrupting capability, bolt-in mounting, and operation at up to 600VAC or 480VDC. Rather than choosing a replacement by amperage alone, the KLPC600 gives you a specific combination to match: 600A continuous current, Class L configuration, time-delay operation, voltage ratings, interrupting ratings, and bolt-in construction. That combination makes KLPC600 a clearly defined choice when the equipment specification calls for this particular style and rating of Class L fuse—not simply "a 600 amp fuse."

Key Features and Benefits

• 600A continuous current rating for equipment specifically designed to use a 600-amp Class L fuse.
• Handles systems rated up to 600VAC within the manufacturer's specified AC limits.
• Also rated for a maximum of 480VDC, giving the fuse defined AC and DC operating parameters.
• The time-delay opening characteristic helps accommodate temporary current surges rather than responding like a fast-acting fuse.
• The manufacturer specifies a minimum ten-second time delay at 500% of rated current for the KLPC series.
• The current-limiting design provides additional short-circuit protection for appropriately specified equipment.
• Bolt-in construction provides an important physical compatibility point when replacing an existing Class L fuse.
• Non-indicating configuration suits equipment where an integral fuse-status indicator is not specified.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses. The supplied information further states that the series provides a minimum ten-second time delay at 500% of rated current while retaining its specified current-limiting characteristics. An individual UL listing number specifically for KLPC600 is not included in the supplied product information, so no catalog-specific listing number is assumed.

Where It Works Best

The KLPC600 600A Class L fuse is best suited to electrical equipment specifically requiring a 600A, time-delay, current-limiting Class L fuse with bolt-in mounting and corresponding electrical ratings. Its time-delay characteristic is particularly relevant where the equipment specification calls for temporary overcurrent tolerance rather than fast-acting operation.
