KRP-C-3500SP - 3500Amp Fuse

KRP-C-3500SP - 3500Amp Fuse

When your application calls for serious current capacity, the Eaton Bussmann KRP-C-3500SP is built for the job. This 3500A Class L fuse is a current-limiting, time-delay fuse rated at 600V, with a 300 kAIC interrupting rating at 600 Vac. The time-delay characteristic gives the fuse a 4-second minimum response at 500% of rated current, helping it tolerate temporary overcurrent conditions rather than reacting immediately to every short-duration surge. That combination makes the KRP-C-3500SP particularly relevant for compatible large distribution switchboards, power panelboards, and large machinery disconnects.

Key Features and Benefits

• 3500A current rating meets the needs of compatible high-amperage electrical equipment.
• 600V rating for systems requiring this voltage class.
• Current-limiting design helps limit fault-current effects during qualifying overcurrent events.
• Time-delay operation allows the fuse to tolerate temporary overcurrents that can occur during normal equipment operation.
• Eaton's KRP-C technical data specifies a 4-second minimum time delay at 500% of rated current.
• Class L construction makes it suitable for equipment specifically designed for Class L fuses.
• The bolted blade-end x bolted blade-end connection provides the required format for compatible equipment.
• Non-indicating design for installations that do not require an integral fuse-status indicator.

Material Compliance and Certifications

The Eaton Bussmann KRP-C-3500SP is RoHS compliant and CE marked, according to the manufacturer information supplied for this model. Check these compliance details when a facility, project specification, or replacement requirement calls for specific material or conformity standards.

Where It Works Best

The KRP-C-3500SP belongs in compatible high-current electrical equipment requiring a 3500A, 600V Class L time-delay fuse. Eaton specifically lists large distribution switchboards, large machinery disconnects, and power panelboards among its applications. Its time-delay behavior can be useful in systems where brief overcurrent conditions are expected, while its current-limiting characteristics and 300 kAIC interrupting rating at 600 VAC address higher fault-current conditions.
