KLPC1200 - 1200Amp Fuse

KLPC1200 - 1200Amp Fuse

The KLPC1200 is built for electrical equipment that specifically requires a 1200A Class L time-delay fuse with high interrupting capability and bolt-in mounting. Rated for up to 600VAC and 480VDC, this POWR-PRO fuse combines time-delay operation with current-limiting performance. The manufacturer specifies a minimum 10-second time delay at 500% of rated current, helping the KLPC series ride through temporary overcurrent conditions while retaining its specified protective characteristics. If you're matching the KLPC1200 as a replacement, check more than the 1200A rating—fuse class, voltage, interrupting rating, time-delay characteristic, and bolt-in configuration must match the equipment requirements.

Key Features and Benefits

• 1200A continuous current rating for equipment designed around a 1200-amp Class L fuse.
• The Class L fuse design provides the electrical and physical characteristics needed for compatible Class L installations.
• The time-delay opening characteristic helps accommodate temporary overcurrent conditions, per the manufacturer's specified time-current performance.
• Provides a minimum 10-second time delay at 500% of rated current, as specified for the KLPC series.
• 600VAC maximum voltage rating supports compatible high-amperage AC electrical systems.
• 480VDC maximum voltage rating adds DC capability where the equipment and system requirements match the fuse ratings.
• The current-limiting design is intended to restrict peak let-through current during applicable fault conditions.
• Bolt-in mounting provides the physical installation method for the KLPC1200.
• The KLPC1200 is non-indicating, so it does not include a 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. The supplied information further identifies the KLPC series as providing a minimum 10-second time delay at 500% of rated current while delivering current-limiting performance.

Where It Works Best

The KLPC1200 is best suited to electrical equipment specifically designed for a 1200A Class L, time-delay, current-limiting fuse using a bolt-in mounting arrangement. Its time-delay characteristic is particularly relevant where the specified protection scheme needs to tolerate temporary current conditions without sacrificing the fuse's required Class L protective characteristics.
