Product Description
The Bussmann LPS‑RK-200 is a heavy‑duty, dual‑element, current‑limiting, time‑delay fuse — part of the Low‑Peak (RK1) series. It provides strong overload and short‑circuit protection for large industrial and commercial electrical systems. The fuse is designed to handle high inrush currents (e.g. from motors or transformers) without nuisance blowing, while offering fast interruption under fault conditions. Because of its high interrupt rating and robust design, it’s ideal for power panelboards, switchboards, motor control centers, feeders, and large machinery disconnects.

Key Features
-
Dual‑element time‑delay design — tolerates startup or inrush currents (motors, transformers) without nuisance fuse trips.
-
Current‑limiting performance — reduces let‑through fault energy, protecting downstream wiring and equipment from damaging thermal or magnetic stress.
-
High interrupt rating (300 kA AC / 100 kA DC) — capable of safely handling heavy fault currents in industrial environments.
-
Class RK1 cartridge format — widely accepted standard size for large‑scale power protection, simplifies fuse holder inventory.
-
Selective coordination advantage (2:1 ampacity ratio across Low‑Peak family) — simplifies sizing for system coordination and helps avoid widespread outages.
-
Suitable for heavy‑duty applications — feeders, large distribution panels, motor control centers, service‑entrance protection, and industrial switchboards.
