Bullet Fuses ECNR3 Fuse 250V 3A RK5 Edison Fusegear (Box of 10)

Bullet Fuses ECNR3 Fuse 250V 3A RK5 Edison Fusegear (Box of 10)

The Bullet Fuses ECNR3 are high-quality, dual-element, time-delay fuses designed to provide reliable overcurrent protection in various electrical applications. Rated at 3 amperes and 250 volts AC (125 volts DC), these Class RK5 fuses are ideal for safeguarding circuits with both inductive loads, such as motors and transformers, and non-inductive loads like lighting and heating systems.

Key Features

• Dual-Element Design: Offers superior protection by combining separate overload and short-circuit elements, allowing for closer sizing to the running ampacity of inductive loads.
• Time-Delay Capability: Provides a minimum time-delay of 10 seconds at five times the fuse rating, effectively handling temporary motor overloads and surge currents without unnecessary fuse openings.
• High Interrupting Rating: Capable of interrupting up to 200,000 amperes, ensuring robust protection against high fault currents.
• Compact Dimensions: Measures 0.56 inches in diameter and 2 inches in length, facilitating easy installation in various fuse holders.
• Compliance and Certification: UL Listed and CSA Certified, meeting stringent safety and performance standards.

Applications

These fuses are recommended for use in AC power distribution system mains, feeders, and branch circuits where the available short-circuit current does not exceed 200,000 RMS symmetrical amperes. They are particularly suitable for circuits with inductive loads, such as motors and transformers, as well as non-inductive loads like lighting and heating systems.
