KLPC1400 - 1400 Amp Fuse

KLPC1400 - 1400 Amp Fuse

When your equipment calls for a 1400A Class L fuse, amperage is only the first step in checking compatibility. The KLPC1400 is a Class L time-delay, current-limiting fuse from the KLPC POWR-PRO series, designed for bolt-in mounting and rated for up to 600VAC and 480VDC. For a replacement or equipment match, verify the complete set of requirements—1400A rating, Class L configuration, voltage, interrupting capability, time-delay characteristics, and bolt-in mounting—rather than choosing by amperage alone.

Key Features and Benefits

• 1400A continuous current rating for electrical equipment specifically designed around this Class L amperage.
• Time-delay opening characteristics help the fuse accommodate temporary overcurrent conditions in accordance with its specified time-current performance.
• The KLPC series provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer.
• The current-limiting design helps control damaging peak let-through current during applicable short-circuit conditions.
• Rated for a maximum of 600VAC, giving the KLPC1400 a clearly defined AC operating limit.
• Also rated to 480VDC maximum for compatible DC equipment.
• Bolt-in construction and mounting provide a defined physical format for equipment compatibility.
• The KLPC1400 is non-indicating, an important detail when matching an existing fuse specification.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses and describes the series as having specification-grade construction and performance. The manufacturer further states that KLPC series fuses provide a minimum 10-second time delay at 500% of rated current while maintaining their stated current-limiting performance.

Where It Works Best

The KLPC1400 suits electrical equipment that requires a 1400A Class L, time-delay, current-limiting fuse with bolt-in mounting. Its manufacturer-specified time delay can be valuable in systems where temporary overcurrent conditions are expected, while the current-limiting design addresses the very different demands of short-circuit conditions.
