Eaton 250A Tag Fuse 31 x 131 mm 690V

This tag fuse is a high-current protective device designed for industrial electrical systems, intended to interrupt overcurrents and protect downstream equipment in three-phase and heavy-duty installations. It is constructed to function at elevated voltages and integrate with standard NH fuse holders used in panel and switchgear environments.

• 250A rating delivers secure protection for high-current circuits
• AM time characteristic provides protection for motor and general loads
• 690V capability supports use in medium-voltage distribution
• High rupturing capacity limits fault energy during short-circuits
• NH2 size ensures compatibility with NH2 holder systems

• Suitable for motor control and starter protection in industrial plants
• Ideal for distribution boards in factories and process facilities
• Used with NH2 switchgear in automation control panels
• Can be used for protection of transformers and feeders in electrical rooms

It is manufactured to recognised European and international fuse standards including IEC 60269‑1 and IEC 60269‑2 and aligns with DIN 43620 dimensional conventions for interchangeability.

The unit conforms to an NH2 format with a Compact profile suitable for NH-type holders and has a length of 150mm to fit standard NH fuse assemblies.

The AM characteristic offers moderate time-delay behaviour allowing short-duration inrush currents, such as motor starts, while providing discrimination against sustained overloads.

Yes, the device is specified with a high rupturing capacity to safely interrupt high prospective fault currents common in industrial distribution.
