FLSR175-ID - 175Amp Fuse

FLSR175-ID - 175Amp Fuse

The Littelfuse FLSR175ID fuse is purpose‑built to help protect your heavy‑duty power systems without drama. Rated at 175 amps and 600 volts AC (300 volts DC), this Class RK5 time‑delay (Slo‑Blo) fuse features dual‑element technology and a built‑in blown‑fuse indicator so you get fast, easy status checks and fewer surprise shutdowns. With easy knife‑blade terminals, it installs cleanly into high‑capacity circuits and stands up to the demands of industrial environments. If your application involves motor starts, large transformers, or critical distribution panels, the FLSR175ID gives you dependable interruption of overloads and short‑circuits—so you can stay focused on uptime instead of chasing faults.

Key Features & Benefits

• Integrated fuse‑status indicator: Provides a quick visual check when a fuse has blown, cutting diagnostic time and reducing downtime.
• Dual‑element current‑limiting design: Delivers strong protection against both overloads and short‑circuit events, helping shield downstream equipment.
• Knife‑blade terminals: Offer a strong, low‑resistance connection suited to high‑current installations and harsh conditions.
• Time‑delay (Slo‑Blo) characteristic: Allows the fuse to ride through short transient overloads—such as during motor start‑up or transformer energization—so you avoid nuisance openings.
• High interrupting capacity: Designed to clear fault currents quickly, supporting the safety and reliability of your system.
