KLPC400 - 400Amp Fuse

KLPC400 - 400Amp Fuse

When your equipment calls for a 400A Class L fuse, matching the amp rating is only the beginning. The KLPC400 is a 400-amp time-delay, current-limiting fuse designed for compatible Class L applications, with maximum ratings of 600VAC and 480VDC and a bolt-in configuration.

Key Features and Benefits

• 400A continuous current rating for equipment specifically designed around this Class L fuse rating.
• Class L configuration provides a critical compatibility point when identifying a replacement fuse.
• Handles applications with a specified maximum voltage of 600VAC.
• Rated up to 480VDC for compatible DC equipment.
• The time-delay opening characteristic provides different operating behavior than a fast-acting fuse.
• KLPC series construction provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer.
• Current-limiting design is part of the KLPC series' specified performance.
• Bolt-in construction and mounting make the physical installation format clear when checking equipment compatibility.
• Match the non-indicating configuration to the requirements of the equipment being serviced.

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 while retaining current-limiting characteristics. The supplied KLPC400 information does not provide an individual UL listing number, so no product-specific listing number is assumed.

Where It Works Best

The KLPC400 suits electrical equipment that requires a 400A Class L time-delay, current-limiting fuse with bolt-in mounting. It sits within the manufacturer's stated KLPC series range of 200 through 6000 amps, making this catalog number the 400A option described in the supplied product data.

For AC equipment, verify the 400A continuous current rating, 600VAC maximum voltage, required AC interrupting rating, Class L configuration, time-delay characteristic, and bolt-in mounting. For compatible DC equipment, confirm requirements against the 480VDC maximum rating and 20,000A interrupting rating at 480VDC.
