KLPC900 - 900Amp Fuse

KLPC900 - 900Amp Fuse

When your equipment calls for a 900A Class L fuse, getting the catalog number and amperage right is only part of the replacement check. The KLPC900 is a 900-amp POWR-PRO Class L fuse with time-delay operation, current-limiting performance, 600VAC and 480VDC maximum voltage ratings, and bolt-in construction. For maintenance, replacement, or equipment matching, confirm the KLPC900's Class L configuration, voltage ratings, interrupting requirements, time-delay characteristic, bolt-in mounting, and non-indicating design before installation.

Key Features and Benefits

• 900A continuous current rating for electrical equipment designed around a 900-amp Class L fuse.
• Class L configuration provides defined electrical and physical characteristics for accurate replacement matching.
• Rated for a maximum of 600VAC.
• Supports compatible DC equipment up to a specified 480VDC maximum.
• Time-delay opening characteristic makes operating behavior an important part of proper fuse selection.
• The KLPC series provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer.
• Current-limiting design is a specified performance characteristic of the KLPC series.
• Bolt-in construction and mounting should match the equipment's existing fuse arrangement.
• Non-indicating design is another detail to verify when matching the KLPC900 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 combines current-limiting performance with a minimum 10-second time delay at 500% of rated current. The supplied information does not provide an individual UL listing number specifically for the KLPC900, so no catalog-specific certification number is assumed here.

Where It Works Best

The KLPC900 900A Class L fuse suits electrical equipment designed for a 900A, time-delay, current-limiting Class L fuse with bolt-in mounting. Match the full specification—not just the 900A rating—because fuse class, opening characteristic, voltage, interrupting capability, and physical mounting all affect suitability.
