KLPC1100 - 1100Amp Fuse

KLPC1100 - 1100Amp Fuse

When a high-amperage circuit specifically calls for a 1100A Class L time-delay fuse, the KLPC1100 gives you a very particular set of ratings to match. The KLPC1100 is a 1100-amp POWR-PRO Class L fuse with a maximum rating of 600VAC and 480VDC, a bolt-in configuration, and a non-indicating design. For replacement work, don't stop at the 1100A marking. Confirm the fuse class, AC or DC voltage, applicable interrupting rating, time-delay characteristic, bolt-in mounting, and equipment specifications before installation.

Key Features and Benefits

• 1100A continuous current rating for equipment designed around an 1100-amp Class L fuse.
• Class L configuration provides a clearly defined fuse class for accurate replacement matching.
• Time-delay operation is designed to tolerate temporary overcurrent conditions according to the manufacturer's specified time-current characteristics.
• Provides a minimum 10-second time delay at 500% of rated current, based on the manufacturer's KLPC series specifications.
• Rated for up to 600VAC, supporting equipment requiring this AC voltage class and the corresponding fuse characteristics.
• Current-limiting design helps limit peak let-through current during applicable fault conditions.
• The manufacturer states that, on average, KLPC series peak let-through currents are 10% lower than other time-delay Class L fuses.
• Bolt-in mounting provides the physical installation format specified for the KLPC1100.
• Non-indicating design means the fuse does not include a built-in blown-fuse indication feature.

Material Compliance and Certifications

The supplied manufacturer information identifies the KLPC series as UL Listed Class L fuses. It also states that KLPC series specification-grade construction and performance meet or exceed stringent project specifications. In addition, the manufacturer describes the KLPC series as providing a minimum 10-second time delay at 500% of rated current while maintaining current-limiting performance.

Where It Works Best

The KLPC1100 suits electrical equipment designed for a 1100A Class L time-delay, current-limiting fuse with bolt-in mounting. The combination of high current capacity and time-delay behavior makes the exact application requirements especially important; amperage alone doesn't tell you whether a fuse is a proper match.
