ECSR80 - 80Amp Fuse

ECSR80 - 80Amp Fuse

The Eaton Edison ECSR80 is a dependable 80‑amp, dual‑element time‑delay fuse engineered to protect demanding commercial and industrial electrical systems. Built to handle 600 V AC circuits, this Class RK5 fuse is ideal when you need to guard against both prolonged overloads and sudden short circuits. Thanks to its 10‑second time delay at 500% overload, the ECSR80 absorbs startup surges from motors, transformers, and heavy-duty equipment without tripping unnecessarily — helping you avoid costly downtime. Its compact, blade-end construction ensures a snug, vibration-resistant fit inside heavy-duty fuse blocks, making it a great choice for panel installations where space is tight but reliability can’t be compromised.

Key Features and Benefits

• Time‑Delay Protection: Let circuits endure startup inrush currents without unlatching, reducing unwanted shutdowns.
• Dual‑Element Design: Combines fast fault interruption with slow overload response — giving balanced protection that covers a wide range of electrical hazards.
• 200 kAIC Interrupt Rating: Capable of safely interrupting high-energy faults to shield equipment and wiring from damage.
• Blade‑End Configuration: Provides a secure, snug fit in industrial fuse holders, resisting loosening even under vibration or heavy load.
• Compact & Lightweight: At approximately 5 inches long and 0.4 pounds, it’s easy to install in panels or load centers with limited space.
