Eaton 250A Tag Fuse NH3 690V

This tag fuse provides overcurrent protection in low- and medium-voltage distribution systems, designed for use where a robust, replaceable protective element is required. It is intended for installations in power generation and industrial networks, offering a defined breaking characteristic for general-purpose circuit protection up to high voltage levels.

• 250A rated current delivers consistent protection for heavy circuits
• 690V voltage capability supports high-voltage distribution systems
• gG (general-purpose) breaking characteristic protects conductors and equipment
• NH3 format enables compatibility with standard NH fuse holders
• Conforms to DIN 43620 for standardised NH mounting and interchangeability
• Meets IEC 60269-1 and IEC 60269-2 for internationally recognised performance

• Suitable for solar PV arrays and inverter protection
• Ideal for wind turbine electrical protection systems
• Used for utility distribution board protection duties
• Can be used for industrial motor and feeder circuits
• Suitable for protection in automation and control panels

The unit uses an NH3 size envelope with an overall length of 150mm for insertion into NH fuse holders and switchgear adaptors.

The gG designation indicates a full-range breaking capability for both overloads and short-circuits, providing conductor and equipment protection across typical fault profiles.

Compliance with DIN 43620 and the IEC 60269 series ensures dimensional and performance compatibility with standard NH systems meeting those standards.

Its voltage rating to 690V and 250A current capacity make it suitable for integration in hybrid generation distribution circuits where NH3 fuses are required.
