KRP-C-4000SP - 4000Amp Fuse

KRP-C-4000SP - 4000Amp Fuse

Built for high-current electrical applications, the Eaton Bussmann KRP-C-4000SP combines a 4000A amperage rating, 600V voltage rating, and an impressive 300 kAIC interrupting rating at 600 Vac in a Class L configuration. For maintenance teams, electricians, and facility professionals replacing an existing fuse, those numbers matter—but so do the details that determine whether the fuse actually matches the equipment. If you're matching an existing KRP-C-4000SP fuse, check the catalog number along with amperage, voltage, connection style, fuse class, and dimensions to avoid a specification mismatch.

Key Features and Benefits

• 4000A amperage rating supports compatible high-current electrical systems.
• 600V voltage rating meets the requirements of equipment designed for this voltage and fuse configuration.
• 4-second response time at 500% of rated current provides a clearly defined response characteristic for system coordination.
• The Class L configuration makes identification easier when replacing a fuse in equipment that requires this fuse class.
• The bolted blade-to-bolted blade connection provides the arrangement needed for compatible installations.
• Non-indicating design is appropriate where an integral fuse-status indicator isn't required.

Material Compliance and Certifications

The KRP-C-4000SP is RoHS compliant and CE marked, per the manufacturer specifications for this model. These details matter when verifying whether a component meets the material-compliance or conformity requirements for a particular project, facility, or electrical system.

Where It Works Best

The Eaton Bussmann KRP-C-4000SP 4000A fuse is best suited for compatible high-amperage electrical equipment that requires a 600V Class L fuse with a 300 kAIC interrupting rating at 600 Vac. Its 4000A rating puts it firmly in the high-current category. At the same time, the bolted-blade configuration makes it important to confirm the equipment's mounting and connection requirements rather than relying on amperage alone.
