KRP-C-1100SP - 1100Amp Fuse

KRP-C-1100SP - 1100Amp Fuse

At 1100 amps, choosing the right fuse takes more than matching the label number. The KRP-C-1100SP is a Class L fuse rated 1100A at 600VAC and 300VDC, with a 300 kAIC interrupt rating at 600VAC and a 100 kAIC DC interrupt rating. The manufacturer also specifies a 4-second response time at 500%, giving you another important characteristic to compare with the equipment requirements. If you're checking the KRP-C-1100SP as a replacement, don't stop at amperage—verify the Class L configuration, AC or DC voltage requirement, interrupt rating, response characteristic, blade connection, and available mounting space.

Key Features and Benefits

• 1100A current rating for equipment specifically designed around this fuse amperage.
• Class L configuration provides an essential checkpoint when matching an existing fuse or equipment specification.
• Handles systems rated up to 600VAC.
• Also carries a 300VDC rating, making AC/DC compatibility easier to verify from the catalog specifications.
• The 4-second response time at 500% gives you a clear response characteristic to compare with system requirements.
• Confirm the bolted blade-end-to-bolted-blade-end connection against the existing fuse and mounting arrangement.
• Non-indicating design means this model does not provide a built-in fuse-status indicator.
• CE marked according to the supplied manufacturer specifications.
• RoHS compliant.

Material Compliance and Certifications

The supplied product data identifies the KRP-C-1100SP as RoHS-compliant and CE-marked. Those are the compliance details specifically provided for this catalog number.

Where It Works Best

The KRP-C-1100SP best matches electrical equipment that requires a 1100A Class L fuse with the corresponding voltage, interrupt, response, and physical requirements. For AC equipment, confirm the 600VAC rating and 300 kAIC interrupt rating at 600VAC. For DC equipment, check the 300VDC rating and 100 kAIC VDC interrupt specification against the system requirements.

Physical fit deserves attention too. The equipment needs to accommodate the bolted blade end connections and the fuse's 10.75 x 2.78 x 2.78-inch dimensions. Finally, confirm that the specified 4-second response at 500% and non-indicating configuration are appropriate for the equipment being serviced. Matching those details up front is far more reliable than shopping by amperage alone.
