KLPC1000 - 1000Amp Fuse

KLPC1000 - 1000Amp Fuse

For high-amperage circuits requiring a 1000A Class L time-delay fuse, the KLPC1000 combines high interrupting capacity, current-limiting performance, and a construction built for demanding electrical protection. The KLPC1000 is a 1000-amp Class L fuse rated for up to 600VAC and 480VDC, with bolt-in mounting and a non-indicating design. When you're replacing a KLPC1000, matching the 1000A rating is only the beginning—confirm the Class L configuration, voltage, interrupting ratings, time-delay behavior, bolt-in construction, and equipment requirements.

Key Features and Benefits

• 1000A continuous current rating for circuits specifically designed around a 1000-amp Class L fuse.
• Time-delay operation provides a minimum delay of 10 seconds at 500% of rated current, according to the manufacturer's KLPC series information.
• Rated for a maximum of 600VAC and 480VDC, giving the KLPC1000 defined ratings for both AC and DC applications.
• Current-limiting performance is a central feature of the KLPC series, helping control peak let-through current during applicable overcurrent events.
• The bolt-in configuration provides the mounting style specified for this 1000A Class L fuse.
• The non-indicating design means it has no built-in blown-fuse indication feature.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses and states that its specification-grade construction and performance meet or exceed stringent project specifications. For the KLPC1000, the supplied information also provides unusually useful construction detail: 99.9% pure silver links, silver-plated copper end bells, a glass-reinforced melamine body, O-ring seals, and granular quartz filler.

Where It Works Best

The KLPC1000 suits electrical equipment designed for a 1000A Class L, time-delay, current-limiting fuse with bolt-in mounting. Its combination of a 1000A continuous rating, time-delay response, and high AC interrupting values makes it relevant where the equipment specifications call for these exact characteristics rather than simply a fuse with the same amperage.
