Edison ECNR20 250V 20A RK5 Fuse (Box of 10)

Edison ECNR20 250V 20A RK5 Fuse (Box of 10)

The Edison ECNR20 is a dual-element, time-delay fuse designed to provide superior protection for AC power distribution systems. This fuse is ideal for safeguarding mains, feeders, and branch circuits that serve both inductive loads, such as motors and transformers, and non-inductive loads like lighting and heating systems.

Key Features

• Amperage Rating: 20 Amps
• Voltage Rating: 250 VAC / 125 VDC
• Interrupting Rating: 200,000 Amperes RMS Symmetrical
• Class: RK5
• Time-Delay: 8 seconds at 500% of rated current
• Construction: Dual-element design for enhanced overload and short-circuit protection
• Body Material: Fiberglass for durability and reliability
• Dimensions: 0.56 inches in diameter and 2 inches in length

Applications

The ECNR20 fuse is recommended for use in AC power distribution systems where the available short-circuit current does not exceed 200,000 RMS symmetrical amperes. Its time-delay characteristics allow it to handle temporary motor overloads and surge currents, making it suitable for:

• Motor and motor branch circuit protection
• Transformer protection
• Lighting and heating circuits
• General-purpose applications

Benefits

• Provides protection against motor overloads, ground faults, and short circuits
• Helps prevent motor burnout from single phasing in three-phase systems
• Enhances blackout prevention through selective coordination
• Allows for closer sizing to running ampacity of inductive loads, reducing costs and improving overcurrent protection

Each box contains 10 fuses, ensuring you have an adequate supply for multiple applications or replacements.
