KRP-C-1800SP - 1800Amp Fuse

KRP-C-1800SP - 1800Amp Fuse

When you're matching a high-amperage Class L fuse, the catalog number tells only part of the story. The KRP-C-1800SP is a 1800A Class L fuse rated for 600VAC and 300VDC, with a manufacturer-specified interrupt rating of 300 kAIC at 600VAC and 100 kAIC at 300VDC. For anyone replacing an existing KRP-C-1800SP or verifying it against equipment specifications, amperage is just the starting point. The Class L configuration, AC or DC voltage, required interrupt rating, response characteristic, connection style, and physical dimensions should all match the equipment requirements before selecting a fuse.

Key Features and Benefits

• 1800A amperage rating provides a clear starting point when cross-referencing an existing fuse or equipment specification.
• Rated for 600VAC and 300VDC, giving you documented ratings for both AC and DC service.
• Class L fuse construction is an important compatibility detail that should be matched exactly where the equipment calls for this fuse class.
• Manufacturer-listed response time is 4 seconds at 500% of the fuse's rated current.
• Uses a bolted blade-to-bolted blade connection, making connection style another easy specification to verify during replacement.
• Non-indicating configuration clearly identifies the status-indicator design of this catalog number.
• RoHS compliant according to the supplied manufacturer specifications.
• CE marked as documented for the KRP-C-1800SP.

Material Compliance and Certifications

The supplied manufacturer information specifically identifies the KRP-C-1800SP as RoHS compliant and CE marked. These are documented attributes of this catalog number and do not need to be inferred from another product in the KRP-C family.

Where It Works Best

The KRP-C-1800SP is best suited to electrical equipment specifically designed for a 1800A Class L fuse with corresponding voltage, interrupting, physical, and connection requirements. In a 600VAC application, confirm that the equipment's required interrupting capacity matches the stated 300 kAIC at 600VAC rating. For DC service, check both the 300VDC voltage rating and the separately specified 100 kAIC VDC interrupt rating against the system requirements.
