ECNR25 - 25 Amp Fuse

ECNR25 - 25 Amp Fuse

Electrical systems perform best when they're protected by components designed to handle real-world operating conditions. The Eaton Edison ECNR25 Fuse is a 25 Amp Class RK5 dual-element time-delay fuse engineered to provide dependable overcurrent protection while minimizing unnecessary interruptions caused by temporary startup surges. Whether you're protecting motors, transformers, HVAC equipment, or industrial control circuits, the ECNR25 helps keep systems running smoothly by allowing harmless inrush currents to pass while responding quickly to sustained overloads and fault conditions.

Designed for commercial and industrial electrical applications, the Eaton ECNR25 features a 200 kAIC interrupt rating, providing a high level of protection against potentially damaging short circuits. Its dual-element construction delivers enhanced overload tolerance compared to standard fast-acting fuses, helping reduce nuisance fuse replacements and costly downtime. Rated for 250 VAC and 125 VDC systems, this Class RK5 fuse offers a practical balance of equipment protection, reliability, and long service life.
