FAQs
To replace, power down the panel, verify the circuit is de-energized, and remove the failed fuse from the standard 2 in holder. The LPN-RK-15/100SP is a compact, dual-element, non-indicating RK1 class fuse with a 0.15 A rating sized for 250 Vac / 125 Vdc systems. Ensure replacement matches amperage, voltage, and interrupt rating requirements for motor protection.
The fuse provides an interrupt rating of 300 kAIC at 250 Vac and 100 kAIC at 125 Vdc, with a voltage rating of 250 Vac / 125 Vdc. It is time-delay and current-limiting, designed to handle motor inrush while protecting circuits from faults. The 0.15 A rating supports protected signaling and small control circuits in industrial panels.
Yes. The LPN-RK-15/100SP features time-delay, dual-element protection optimized for motor inrush scenarios. Its RK1 class rating and high interrupt capacity help withstand startup surges without nuisance tripping, making it suitable for conveyors, pumps, and other motor-driven equipment in manufacturing environments.
Yes. The fuse is CE marked, aligning with European safety requirements for electrical protection components. This conformity supports compliance in global installations, particularly where European directives govern electrical safety in industrial equipment and panels.
The unit is non-indicating, reducing visual maintenance checks while delivering reliable protection, which decreases downtime from nuisance trips. Its robust interrupt ratings and RK1-class compatibility support longer service intervals, lower replacement costs, and improved return on investment for motor protection strategies in busy production lines.
