KLPC250 - 250Amp Fuse

KLPC250 - 250Amp Fuse

The KLPC250 is a 250A Class L time-delay, current-limiting fuse for your electrical equipment that requires a bolt-in fuse rated up to 600VAC or 480VDC. Part of the KLPC POWR-PRO series, it combines a minimum 10-second time delay at 500% of rated current with the series' current-limiting design. For anyone replacing an existing fuse, the 250A rating is a good starting point—but check Class L compatibility, voltage, interrupting rating, time-delay characteristics, and physical mounting before matching.

Key Features and Benefits

• 250A continuous current rating for equipment designed around this specific fuse rating.
• Class L configuration provides a clear compatibility point for replacement and equipment specification checks.
• The manufacturer identifies time-delay operation 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 a stated performance characteristic of the KLPC POWR-PRO series.
• Handles equipment requirements up to a maximum of 600VAC.
• Also rated for up to 480VDC.
• Bolt-in construction and mounting make the physical format straightforward to verify against existing equipment.
• Consider the non-indicating design when matching an existing fuse or equipment requirement.

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 maintaining its specified current-limiting characteristics. The supplied information does not provide an individual UL listing number specifically for the KLPC250, so no product-specific listing number is assumed.

Where It Works Best

The KLPC250 250A fuse best matches electrical equipment designed for a 250A Class L, time-delay, current-limiting fuse with bolt-in mounting. The manufacturer positions the broader KLPC series for overcurrent protection in circuits from 200 through 6000 amperes, placing the KLPC250 at the lower end of that range.
