KLPC300 - 300Amp Fuse

KLPC300 - 300Amp Fuse

The KLPC300 is a 300A Class L time-delay, current-limiting fuse for electrical equipment that requires a bolt-in fuse rated up to 600VAC or 480VDC. When you're matching the KLPC300 to existing equipment, confirm the fuse class, voltage, applicable interrupting rating, time-delay requirement, bolt-in mounting configuration, and amperage.

Key Features and Benefits

• 300A continuous current rating for equipment designed around this Class L amperage.
• Class L configuration provides a clear identification point for replacement and equipment compatibility.
• Handles applications requiring a fuse rated up to 600VAC.
• 480VDC maximum voltage rating supports compatible DC equipment.
• Time-delay operation is specified as Slo-Blo / Time Lag (T) / Time Delay.
• KLPC series fuses provide a minimum 10-second time delay at 500% of rated current.
• Current-limiting design is part of the KLPC series' specified performance.
• Bolt-in construction and mounting make physical compatibility straightforward to verify against the existing installation.
• The KLPC300 is a non-indicating fuse, an important detail when matching an existing fuse or equipment specification.

Material Compliance and Certifications

The manufacturer identifies the KLPC series as UL Listed Class L fuses and states that the series provides a minimum 10-second time delay at 500% of rated current. The supplied product information does not provide an individual UL listing number for the KLPC300, so do not assume a catalog-specific listing number.

Where It Works Best

The KLPC300 300A Class L fuse is best suited to electrical equipment specifically designed for a 300A, Class L, time-delay, current-limiting fuse with bolt-in mounting. The manufacturer positions the broader KLPC series for overcurrent protection in circuits ranging from 200 through 6000 amperes, with KLPC300 providing the specific 300A configuration described here.

For AC equipment, verify the 300A continuous current rating, 600VAC maximum voltage, applicable AC interrupting requirement, Class L configuration, time-delay characteristic, and bolt-in mounting. For DC equipment, check compatibility with the 480VDC maximum voltage and 20,000A interrupting rating at 480VDC.
