Eaton 355A Tag Fuse 76 x 254 mm 3.6kV

This tag fuse is a high-voltage protective device designed for motor protection duties in industrial electrical systems. It operates at 3.6 kV and is intended to provide reliable interruption capability for circuits where back-up protection is required. The product conforms to British Standard criteria and is suited to installations where a high rupture capability is necessary.

• 355A continuous rating provides defined motor overcurrent protection
• 50 kAIC fault endurance limits prospective fault currents
• Back-up speed offers delayed operation for co-ordination
• High-voltage rating supports 3.6 kV system compatibility
• Cylindrical form factor enables secure cartridge retention

• Suitable for protecting medium-voltage motor feeders in industrial plants
• Ideal for use in switchgear requiring co-ordinated back-up protection
• Used for safeguarding transformers and distribution circuits against sustained overloads
• Can be used for retrofitting older 3.6 kV installations to meet rupture capacity needs

It has a high rupture capacity rated at 50 kAIC, enabling it to clear large fault currents without catastrophic failure.

The back-up operating characteristic allows it to operate after primary protective devices, aiding selective tripping and preventing nuisance isolation.

The unit presents a cylindrical geometry with a nominal 76mm diameter and compatibility with 76 x 254 mm fuse housings for straightforward replacement.

It is specified for use in 3.6 kV networks, making it appropriate for medium-voltage motor protection and related distribution applications.
