Overview
The Eaton Edison ECNR 6/10 fuse is a Class RK5 dual-element, time-delay current-limiting fuse designed for motor circuit protection in industrial and commercial applications. This box of 10 units ensures a ready supply for maintenance and replacement needs. ECNR 6/10 fuses combine superior overload and cycling capabilities with reliable short-circuit protection, making them ideal for demanding electrical systems.
Key Features
- Dual-element construction with ferrule ends for secure contact and consistent performance
- Time-delay (slow-blow) design tolerates motor inrush current while protecting against sustained overloads
- Class RK5 current-limiting rating delivers fast fault clearing to minimize equipment damage
- Non-indicating design; fuse must be visually inspected or tested for status
- 200 kAIC interrupting rating at 250VAC for industrial-grade protection
- 8-second response at 500% load for coordinated motor circuit protection
