Eaton 630 A Fuse Holder, 3P-Pole for NH3, 690 V ac

This fuse holder provides a robust mounting solution for high-current NH3 fuses in industrial electrical systems. It is intended for three-phase installations where secure connection and reliable current interruption are required, operating within low-voltage distribution and motor-control environments.

• Rated for 630A continuous current to handle heavy-load circuits
• Designed for 3-pole configuration to support three-phase protection
• Withstands system voltages up to 690V for versatile network compatibility
• Accepts NH3 size fuses for standardised cartridge replacement
• Fixes with M12 screws for secure mechanical termination
• Complies with IEC/EN 60947 standards for recognised functional performance

• Suitable for main incomer protection in switchboards
• Ideal for motor starter assemblies in manufacturing plants
• Used with isolation and distribution units in automation panels
• Can be used for protective upgrades in electrical distribution cabinets

It carries CE marking and conforms to IEC/EN 60947-1 and IEC 60947-3 standards, indicating adherence to applicable European and international switchgear requirements.

It accepts NH3-format fuses, allowing use of widely available NH3 cartridges for serviceability and straightforward swapping.

Termination uses M12 fixing screws to provide a mechanically robust connection suited to high-current conductors.

It is specified for use at system voltages up to 690V, making it suitable for low-voltage industrial distribution rather than medium-voltage networks.

The holder is designed to carry currents up to 630A, enabling use in substantial power circuits typical in electrical and mechanical industry installations.
