Industrial ECNR200 Time Delay Fuse

ECNR200 is a 200 A, 250 VAC time-delay current-limiting fuse from Eaton's Edison ECNR RK5 family. This dual-element, non-indicating fuse uses blade-end terminals and delivers a 200 kAIC interrupt rating, making it suitable for feeder and branch protection where brief startup surges occur. Rated for up to 250 VAC (with a 125 VDC rating listed in some catalogs), it features a time-delay characteristic that withstands brief overloads—up to 500% for about 10 seconds—to tolerate inrush while protecting circuits. UL-listed and CSA-certified for low-voltage applications, the ECNR200 measures about 8.63 in long with a 2.38 in footprint and is intended for use in RK5 fuse blocks in industrial panels protecting motors, drives, and other high-inrush loads.
