FLSR150-ID - 150Amp Fuse Description
FLSR150-ID - 150Amp Fuse
The 150 Amp 600 Volt Littelfuse FLSR150ID indicating time‑delay fuse delivers exceptional protection and fast diagnostics for demanding industrial and commercial power systems. Built with dual‑element technology and heavy‑duty knife‑blade terminals, this Class RK5 fuse rides through short‑term surges from motors and inductive loads while interrupting sustained overloads and short circuits with precision. Its integrated visual indication means you can spot a blown fuse at a glance—minimizing downtime and accelerating maintenance in time‑critical operations.
Key Features and Benefits
- Slo‑Blo Time‑Delay Operation: Designed to tolerate inrush currents without tripping, the FLSR150ID supports smooth motor start‑ups and avoids unnecessary interruptions.
- Visual Indication: Comes with an indication window that turns dark when the fuse has blown, enabling quick identification and replacement to reduce labour and operational delays.
- Dual‑Element Construction: Enhances protection by offering both time‑delay for overloads and fast action for short circuits—helping preserve downstream equipment and system integrity.
- Knife‑Blade Terminals: Provides secure, efficient installation and removal in blade‑style holders—ideal for high current, high demand applications.
