KLPC4500 - 4500Amp Fuse

KLPC4500 - 4500Amp Fuse

When your equipment calls for a 4500A Class L fuse, matching the amp rating is only part of the job. The KLPC4500 is a POWR-PRO time-delay, current-limiting fuse rated for up to 600VAC and 480VDC, with a bolt-in configuration designed for equipment requiring this specific Class L format. For replacement work, verify the complete electrical and physical specification—not just 4500A—including voltage, interrupting requirements, Class L configuration, opening characteristic, bolt-in mounting, and non-indicating design.

Key Features and Benefits

• 4500A continuous current rating for electrical equipment specifically designed around this Class L fuse rating.
• 600VAC maximum voltage rating supports compatible AC systems within the manufacturer's stated limits.
• 480VDC maximum voltage rating provides a clearly defined DC operating limit.
• Time-delay opening characteristic is specified as Slo-Blo / Time Lag (T) / Time Delay.
• The KLPC series provides a minimum 10-second time delay at 500% of rated current, according to the manufacturer.
• Current-limiting performance is a defining characteristic of the KLPC series.
• Bolt-in construction gives technicians an important physical compatibility point to confirm during replacement.
• Match the non-indicating design when the existing equipment specification calls for this configuration.

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 also providing current-limiting performance. The supplied specifications do not provide an individual UL listing number specifically for the KLPC4500, so no catalog-specific certification number is assumed.

Where It Works Best

The KLPC4500 suits electrical equipment that requires a 4500A Class L time-delay, current-limiting fuse with bolt-in mounting. The manufacturer places the KLPC family within its overcurrent-protection range for circuits from 200 through 6000 amperes, putting the KLPC4500 toward the upper end of that stated series range.

For AC applications, confirm equipment requirements against the 600VAC maximum rating and the applicable supplied AC interrupting value. For DC service, verify the 480VDC maximum voltage and 20,000A interrupting rating at 480VDC. The Class L format, time-delay characteristic, current-limiting requirement, bolt-in construction, and non-indicating design must also match the equipment specification.
