High current capability and robust interrupt performance: The 1350 A amperage rating provides direct protection at the source for large feeders, reducing conductor damage and downstream faults. Business impact is improved uptime and simplified coordination with upstream protective devices, enabling designs that scale with future load growth. Applications include motor-control centers and high-load distribution panels where reliability is non-negotiable and downtime costs are measurable. Time-delay operation minimizes nuisance tripping during inrush events, delivering smoother motor starts and energy management benefits. The business result is lower maintenance costs and fewer unplanned outages on critical lines. Class L designation with current-limiting action reduces arc energy and enhances personnel safety during disconnection, a feature that aligns with strict industrial safety programs in manufacturing and process industries. Installation is straightforward thanks to bolted blade end connections and standard packaging, which reduces commissioning time and ensures consistent electrical connections. RoHS and CE compliance underpin cross-market applicability, helping integrators meet regulatory requirements without redesigns. The fuse’s dimensions (10.75 in length) and bolted-end configuration support a wide range of enclosure layouts, delivering compatibility with legacy and new builds alike. These attributes collectively translate into lower total cost of ownership through longer intervals between replacements and easier proactive maintenance planning.

FAQs
Install the KRP-C-1350SP using its bolted blade end connections to ensure a secure electrical interface. Verify enclosure space for the 10.75 in length and 3.03 in width/height, and align with the panel’s bus bars. Use appropriate torque values per your enclosure spec and follow standard electrical safety procedures. Refer to the datasheet 1008 for mounting guidance and clearances around the fuse for heat dissipation and service access.
Key specs include a 1350 A amperage rating with an interrupt rating of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC, plus a 4-second response time at 500% overload. The 600 VAC and 300 VDC voltage ratings define operating limits, while the Class L designation indicates time-delay protection suitable for inrush conditions in motors and feeders.
Yes. The high current rating, Class L time-delay characteristic, and bolted end connections make it ideal for motor control centers and high-load feeders. Its current-limiting capability helps manage arc energy during faults, while the 600 VAC / 300 VDC ratings support common industrial distribution scenarios. It also aligns with RoHS and CE requirements for European and global installations.
Yes. The KRP-C-1350SP is CE marked and RoHS compliant, ensuring regulatory approval across many international markets and supporting environmentally responsible design practices. This compliance simplifies procurement for global projects and reduces risk during audits and supplier assessments.
The combination of a high interrupt rating, current-limiting action, and time-delay protection reduces unplanned outages and arc energy during faults, leading to lower maintenance costs and higher uptime. Although the provided data sheet lists no warranty, the device’s durability and regulatory compliance contribute to a favorable total cost of ownership in high-demand electrical systems.
