Eaton xEffect Accessories Series Fuse Holder, 630A Current Rating, 690V Voltage - 289018 GSU3


This fuse holder provides a secure mounting solution for NH3-format fuses in three-pole installations within industrial electrical systems. It is designed to accommodate high-current protection devices and to operate across typical equipment environments where elevated voltage and robust current handling are required.

Features & Benefits


• Rated for 630 A continuous current ensuring high-current protection
• Accepts NH3 fuse elements compatible with NH format fuses
• Suitable for systems up to 690V enabling medium-voltage applications
• Three-pole configuration allowing simultaneous trip of all phases
• M10 fixing screw compatibility for robust mechanical attachment
• Operates between -25 °C and 55 °C for diverse ambient conditions

**Applications**


• Suitable for distribution boards in factory automation systems
• Ideal for protection of motor supplies in mechanical plants
• Used for high-current circuits in electrical switchgear
• Can be used for retrofit of NH3 fuse protection in control panels

How does the design handle thermal stress during heavy loads?


The specified operating temperature range indicates suitability for ambient conditions where heat dissipation and continuous 630 A loading are managed within -25 °C to 55 °C limits.

What fixing method ensures secure installation in switchgear?


The holder accepts M10-size fixing screws, enabling firm mechanical fastening to mounting plates or busbar supports.

Can it be deployed in three-phase distribution systems?


Yes, the device is a three-pole unit intended for coordinated phase protection in three-phase electrical networks.
