FLSR080-ID - 80Amp Fuse

FLSR080-ID - 80Amp Fuse

Power up your industrial system with confidence using the Littelfuse FLSR080ID Indicating Class RK5 fuse. Engineered for heavy environments where reliability is non‑negotiable, this 80 amp continuous fuse features knife‑blade terminations for secure, vibration‑resistant connections and dual‑element, time‑delay (Slo‑Blo) technology that tolerates large inrush currents—ideal when switching motors, transformers, or compressors. And because downtime hits the bottom line, the built‑in visual indicator lets you instantly see if a fuse has blown—no guessing, no delay in maintenance. When you install the FLSR080ID, you’re choosing a fuse designed to go unnoticed until it’s needed—and to keep your equipment running safely until then.

Key Features and Benefits

• Heavy‑duty knife‑blade terminals: Ensure a tight, secure connection even under vibration‑prone industrial conditions.
• Dual‑element, time‑delay operation: Gives you protection against both overloads and shorts, while accommodating startup surges without nuisance trips.
• Integrated blown‑fuse visual indicator: Simplifies maintenance: you see at a glance when replacement is needed, reducing diagnostic time and production delays.
• Class RK5 current‑limiting performance: Provides high‑capacity fault handling, reducing risk of damage and helping prolong equipment life.
