FLSR025-ID - 25Amp Fuse

FLSR025-ID - 25Amp Fuse

The FLSR025‑ID 25 Amp Fuse from Littelfuse is engineered to deliver elite protection for demanding industrial and commercial electrical systems. Ideal for guarding motor control centers, switchboards, and HVAC distribution panels, this dual‑element time‑delay cartridge fuse excels at intercepting both short‑circuit surges and sustained overloads—helping you preserve uptime and extend equipment life. The built‑in visual indicator offers immediate blown‑fuse status, enabling faster diagnostics and reduced downtime. With a 600 V AC / 300 V DC rating and current‑limiting construction, it’s a trustworthy choice for critical infrastructure applications where reliable performance and safety are non‑negotiable.

Key Features and Benefits
