Eaton 6.3A 24kV AC Medium Acting Cartridge Fuse, 51 mm Diameter, 442 mm Length 24TDMEJ6-3

Eaton 24TDMEJ6-3 6.3A Cartridge Fuse is a high-voltage protective component designed to interrupt fault currents in electrical systems operating at 24kV AC. Featuring a medium acting characteristic, this fuse balances the need to handle inrush currents while protecting equipment from sustained overloads. Its cylindrical shape with a 51 mm diameter and length of 442 mm allows for easy integration into existing high-voltage fuse holders and assemblies.

This fuse is part of the Bussmann series and is engineered to meet DIN, IEC, and VDE standards, ensuring compliance with international safety and performance guidelines. Eaton, formerly Bussmann, offers this product primarily for industrial and utility applications where protection coordination and reliable operation under high voltage are critical.

Typical use cases include protection of feeders in medium-voltage distribution networks, switchgear assemblies, and outdoor transformer protection. It is also suitable for use with industrial automation equipment requiring robust high-voltage overcurrent protection. Maintenance and refurbishment operations at electrical plants commonly utilize this fuse as a replacement or spare part.

The medium acting timing characteristic accommodates short-duration surges during motor starting or transformer energisation by allowing inrush current to pass while effectively clearing sustained overloads, thereby reducing nuisance trips.

Its physical dimensions, 51 mm diameter and 442 mm length, must be considered when selecting compatible fuse holders or cartridge assemblies for installation. Designed for operation at 24kV AC to protect high-voltage electrical circuits.

Nominal current rating of 6.3A ensures reliable fault current interruption. Medium acting fuse characteristic balances surge tolerance and effective protection. Cylindrical cartridge shape with 51 mm diameter fits standard high-voltage housings.

Overall length of 442 mm enables compatibility with long cartridge assemblies. Meets DIN, IEC, and VDE standards for safety and performance. Ideal for protecting feeders, switchgear, and outdoor transformers in medium-voltage distribution systems.
