FAQs
Install the LPN-RK-110SP-TP in a standard Bussmann RK1 fuse holder or compatible panel-fuse mounting. Ensure correct polarity isn’t a concern since fuses are non-polarized, confirm the 7.13 in length fits your holder, and secure with proper terminal contact to achieve the 110 A rating and eligible current-limiting protection.
Best suited for motor drives, industrial controls, control panels, conveyors, pumps, and other high-inrush power circuits where reliable startup protection and fast fault containment are critical, thanks to its time-delay and current-limiting characteristics.
Amperage rating is 110 A. Voltage rating is 250 Vac and 250 Vdc. Interrupt ratings are 100 kAIC at 250 Vdc and 300 kAIC at 250 Vac, providing strong fault protection for demanding industrial systems.
Yes. The fuse is RoHS compliant, and its tin-plated material supports reliability in harsh environments while aligning with environmental regulations.
It combines time-delay operation with current-limiting action in a tin-plated, non-indicating package. Its high inrush motor protection capabilities and standard packaging simplify procurement and integration across multiple panels and OEMs.
