FAQs
LPS-RK-3-2/10SP uses ferrule-end connections and a 5 in length with a 0.81 in width, designed for easy drop-in replacement in standard RK1-compatible enclosures. Its dual-element, time-delay construction supports high inrush scenarios common in motor drives. When selecting, verify panel space, end-cap access, and conductor sizing to maintain fault current coordination and safe servicing practices.
The fuse is rated at 3.2 A with a 300 kAIC interrupt rating at 600 Vac and 100 kAIC at 300 Vdc. It is time-delay and current-limiting, providing selective protection for short circuits while allowing temporary inrush. It is CE marked and classified as RK1, with dual-element protection designed to tolerate normal startup surges without compromising overall system safety.
Yes. The LPS-RK-3-2/10SP is well-suited for motor drives and other high-energy loads due to its time-delay, current-limiting characteristics and high interrupt ratings. Its compact ferrule-end design and electrically isolated end caps improve installation reliability and safety in harsh environments, while CE compliance supports regulatory acceptance in industrial facilities.
This fuse is CE marked and part of the Class RK1 family, indicating robust industrial protection standards. It employs a non-indicating design with electrically isolated end caps for safe maintenance. While it does not list other certifications in the data, CE marking and RK1 classification are key indicators of suitability for European equipment and standard control-panel protection.
The 3.2 A LPS-RK-3-2/10SP provides reliable protection against short circuits, reducing unplanned downtime and potential equipment damage. Time-delay protection minimizes nuisance trips during startup, lowering maintenance interventions. Its durable RK1 design and ferrule ends simplify replacement in field and factory repairs, contributing to lower lifecycle costs in motor control and power distribution systems.
