ECNR12 - 12 Amp Fuse

ECNR12 - 12 Amp Fuse

The Eaton Edison ECNR12 Fuse is designed for electrical systems that need dependable protection without unnecessary downtime. Rated at 12 amps and built as a Class RK5 dual-element fuse, the ECNR12 helps protect motors, HVAC equipment, pumps, compressors, and other electrical equipment from damaging overloads and short-circuit events while allowing temporary startup surges to pass without causing nuisance fuse openings.

Built to handle demanding environments, the ECNR12 features a 200 kAIC interrupting rating and is rated for 250 VAC and 125 VDC applications. Its non-indicating, non-current-limiting construction makes it well suited for installations where maintaining compatibility with existing system specifications is important. Whether you're replacing an existing fuse or maintaining critical electrical infrastructure, the Eaton ECNR12 delivers the dependable circuit protection professionals rely on to keep equipment operating safely and efficiently.
