Eaton Cartridge Fuse 20A Current Rating, Time Delay, Fibre Body, 10 x 38 mm, 500V AC FNQ-20

Eaton FNQ-20 Cartridge Fuse is engineered to deliver time-delayed overcurrent protection for electrical systems operating up to 500V AC. This fuse features a fibre body that provides electrical insulation and reduces thermal conduction, thereby maintaining predictable melting behavior under fault conditions. Its 20A current rating and T speed (slow-blow) characteristic make it ideal for protecting motor control circuits and industrial automation equipment against temporary inrush currents without nuisance tripping.

The 10 x 38 mm cartridge format allows for seamless integration into standard fuse clips and holders commonly found in industrial control panels. Eaton’s FNQ series meets the UL 248-14 safety standard, ensuring reliable and standardized performance in demanding applications.

This time delay fuse is particularly suited for applications that require coordination with downstream devices, providing controlled interruption during sustained overloads. Its robust construction and slow-blow behavior facilitate selective protection coordination, enhancing system durability and uptime.

Applications include industrial power distribution within control panels, motor startup surge protection, and equipment where intermittent current surges occur. The fibre material envelope offers lightweight handling while ensuring electrical safety standards are met.

Provides time-delayed overcurrent protection suitable for circuits with temporary surges. Fibre body construction ensures electrical insulation and lightweight handling. Calibrated T speed slow-blow design prevents nuisance tripping on motor start-ups.
