Reliance ECNR 2-8/10 Dual Element Time-Delay Fuse 250V Class RK5 – Box of 10
The Reliance ECNR 2-8/10 is a dual-element, time-delay fuse designed for 250V applications, classified under Class RK5. This fuse is engineered to provide superior protection for both inductive loads, such as motors and transformers, and non-inductive loads like lighting and heating systems.
Key Features
- Dual-Element Construction: Offers enhanced overload and short-circuit protection by incorporating separate overload and short-circuit elements.
- Time-Delay Capability: Provides a minimum time-delay of 10 seconds at 500% of the rated current, allowing for temporary inrush currents without nuisance openings.
- High Interrupting Rating: Capable of interrupting up to 200,000 amperes RMS symmetrical, ensuring reliable performance under high fault conditions.
- Current Limiting: Reduces the let-through energy during short-circuit events, minimizing potential damage to downstream equipment.
- Versatile Application: Suitable for use in AC power distribution system mains, feeders, and branch circuits, as well as for the protection of motors, transformers, and other inductive loads.
