FLSR001-ID - 1 Amp Fuse

FLSR001-ID - 1 Amp Fuse

When you need dependable over‑current protection in a demanding industrial environment, the Littelfuse FLSR001ID delivers. This 1 amp cartridge‑style fuse supports up to 600 VAC (and 300 VDC) and features a dual‑element time‑delay design — making it ideal for circuits with both overload and short‑circuit risk. With the built‑in visual indicator window, you’ll know at a glance if the fuse has operated, helping reduce downtime and accelerate maintenance. Whether you’re safeguarding motor control centers, HVAC systems, or critical distribution panels, this fuse brings solid performance and clarity to your protection strategy.

Key Features and Benefits

• Reliable protection: The dual‑element time‑delay construction handles both inrush currents and full fault current, offering excellent protection from both overloads and short circuits.
• Indicator window for instant status: With a built‑in visual indicator, the fuse lets you quickly verify whether it has operated, so you can troubleshoot faster and keep your system running.
• Time‑delay capability: This feature allows the fuse to tolerate temporary surges (such as motor start‑up inrush) while still responding quickly to real faults—ideal for heavy‑duty industrial loads.
• High interrupting capacity: Rated to safely interrupt fault currents of up to 200,000 A at 600 VAC and 20,000 A at 300 VDC, offering robust protection for mission‑critical applications.
• Industrial construction: Built to meet the demands of harsh environments, this cartridge fuse is engineered for longevity and dependable service.
