Bussmann series Fuseology
Feature: Time-delay, dual-element construction provides reliable protection for motor loads with brief inrush. Business Impact: Enables higher tolerance for startup surges without nuisance trips, extending motor life and reducing unplanned downtime. Application: Well-suited for conveyors, pumps, and fans in manufacturing lines where load profiles exhibit short-lived surges. Feature: Class RK1, current-limiting fuse behavior concentrates fault energy and improves protection coordination. Business Impact: Minimizes conductor stress and arc exposure, enabling tighter protection coordination and longer life in control panels. Application: Ideal for feeder protection, motor starters, and distributed protection across switchgear assemblies. Feature: High interrupt ratings—300 kAIC at 250 Vac and 100 kAIC at 125 Vdc. Business Impact: Delivers robust fault clearance for high-inrush environments, reducing equipment damage and safety risk. Application: Suitable for large motors, hoists, and power supplies in industrial facilities. Feature: RoHS compliant and CE marked. Business Impact: Facilitates global procurement, regulatory alignment, and easier OEM acceptance. Application: Common in machinery destined for international markets and multi-site installations. Feature: Blade-end connections with a compact 7.13 in length and 1.61 in width/height; standard packaging. Business Impact: Simplifies replacement in existing fuse blocks and minimizes downtime due to compatibility with standard enclosures. Application: Fits typical blade-end fuse holders used in control panels and switchgear. Feature: Non-indicating fuse indicator (listed) ensures consistent status checks without added failure modes. Business Impact: Reduces maintenance complexity and inventory variance. Application: Configured for straightforward lifecycle management in industrial environments.

FAQs
The LPN-RK-200SP uses blade-end x blade-end connections and measures 7.13 in long with 1.61 in width and height, designed for standard blade-end fuse holders. It is a Class RK1, 200 A, 250 Vac/250 Vdc device with RoHS and CE markings. When replacing, verify enclosure space, wiring clearance, and that the holder accepts current-limiting time-delay fuses of this class for proper coordination.
This fuse features time-delay, dual-element construction that tolerates transient inrush while preserving protection accuracy. With a 200 A rating and current-limiting characteristics, it reduces nuisance trips during motor start-up and protects conductors from surge energy. It is well-suited for motor drives, conveyors, and other high-inrush machinery in industrial environments.
Ideal for motor-driven loads and control panels, including conveyors, pumps, HVAC equipment, and machine tools. Its Class RK1, 200 A rating, and high interrupt ratings support protection of feeders and motor starters while maintaining selective coordination in centralized control panels and switchgear assemblies.
The LPN-RK-200SP is RoHS compliant and CE marked, aligning with global regulatory requirements. It carries Class RK1 designation for standardized protection and is rated for 250 Vac and 250 Vdc operation, with interrupt ratings up to 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc.
By reducing nuisance trips during motor startup and providing robust protection, it lowers downtime and maintenance costs. The high interrupt rating helps prevent downstream damage, potentially extending equipment life and reducing replacement expenses, while its RoHS/CE compliance supports global procurement and streamlined approvals.
