ECNR20 - 20 Amp Fuse

ECNR20 - 20 Amp Fuse

If you're protecting equipment that experiences startup surges or temporary inrush currents, the Eaton Edison ECNR20 fuse is designed to help keep your operation running smoothly. This 20 Amp Class RK5 dual-element time-delay fuse provides dependable overcurrent protection while allowing motors, HVAC equipment, and other electrical systems the flexibility they need during startup. Instead of opening unnecessarily during brief current spikes, the ECNR20 is designed to tolerate normal inrush conditions while still responding to overloads and short circuits that could damage valuable equipment.

Whether you're maintaining existing equipment, replacing a fuse during routine service, or supporting a new installation, the ECNR20 provides the dependable circuit protection electrical professionals look for every day.

From motor control circuits and HVAC equipment to manufacturing machinery and control panels, the ECNR20 is commonly used in applications where reliable performance is essential.
