KRP-C-4500SP - 4500Amp Fuse

KRP-C-4500SP - 4500Amp Fuse

When you're dealing with a 4500-amp circuit, the details aren't optional—they're the first thing you check. The Eaton Bussmann KRP-C-4500SP is a Class L fuse rated at 4500A and 600V, with a 300 kAIC interrupting rating at 600 Vac. It also has a specified response time of 4 seconds at 500% of rated current. Whether you're checking a replacement component or confirming specifications for compatible electrical equipment, this fuse gives you clearly defined ratings and dimensions to work from. The key is simple: match the catalog number, fuse class, amperage, voltage, interrupting rating, connection, and physical size to the equipment's requirements before installation.

Key Features and Benefits

• 4500A amperage rating for electrical equipment requiring a high-current Class L fuse.
• 600V rating provides a clear match point when checking equipment voltage requirements.
• 4-second response at 500% of rated current gives engineers and maintenance professionals a defined performance characteristic for system coordination.
• Class L fuse configuration simplifies identification when equipment calls for this specific fuse class.
• Bolted blade ends on both sides provide the required connection arrangement for compatible equipment.
• Non-indicating design for applications that don't require an integral fuse-status indicator.

Material Compliance and Certifications

The Eaton Bussmann KRP-C-4500SP is CE marked and RoHS compliant, according to the supplied manufacturer specifications. Check these details when a facility, project, or equipment specification includes material-compliance or conformity requirements.

Where It Works Best

The KRP-C-4500SP 4500A fuse is intended for compatible high-current electrical systems that specifically require a 600V Class L fuse with its stated electrical and physical characteristics. Its 300 kAIC interrupting rating at 600 Vac is especially relevant where available fault current is an important part of the system's protection requirements.

For replacement applications, amperage is only part of the match. Check the existing fuse and equipment requirements for 4500A, 600V, Class L, 300 kAIC at 600 Vac, bolted blade connections, and the specified dimensions. Taking a few moments to verify those details can prevent a wrong-fit replacement and give buyers useful information beyond a bare catalog-number listing.
