ECNR200 - 200Amp Fuse

ECNR200 - 200Amp Fuse

When electrical systems are under pressure, the last thing you want is unnecessary downtime or unexpected failures. That’s where the Eaton Edison ECNR200 fuse really proves its value. Built as a 200 amp Class RK5 dual-element time-delay fuse, it’s designed to handle the tough reality of industrial and commercial power systems—especially where motors, transformers, and other inductive loads create those brief but heavy startup surges.

Whether you're protecting a motor control center, HVAC system, or a critical production line, this fuse is designed to help keep operations running safely and smoothly.

Eaton’s dual-element design also helps reduce nuisance blowouts—something that can save both time and money in the long run. Instead of constantly replacing fuses due to startup spikes, you get more stable system performance and fewer interruptions.
