Industrial ECNR15 Bullet Fuse

ECNR15 is a 15 A, 250 VAC time-delay, current-limiting bullet fuse with ferrule-end connections, designed for feeder and branch protections in industrial electrical systems. As part of Eaton Bussmann's Edison ECNR family, this non-indicating RK5 fuse features a dual-element design and a compact body measured at 0.56 in diameter by 2.0 in long (14.2 x 50.8 mm), suitable for footprint-compatible installations. It offers an interrupt rating up to 200 kAIC and is rated for 250 VAC and 125 VDC, supporting both AC power distribution and select DC circuits. The ECNR15 is specifically a time-delay fuse, balancing brief inrush tolerance with reliable fault protection, which makes it well suited for feeders, motors, transformers, and other inductive loads in industrial equipment, control panels, and HVAC systems where RK5-class protection is required. The bullet-style cartridge uses ferrule terminals, providing a robust, maintenance-friendly connection in densely wired panels.
