Eaton 250A Tag Fuse 217 x 82 x 94 mm 1000V, 167 mm

This tag fuse is a fast-acting photovoltaic protective link designed for use in solar array combiners and disconnects within PV installations. It is intended to interrupt fault currents typical of photovoltaic systems and to isolate strings or sub-arrays in the event of reverse current or multi-array faults. The product is suited to high-voltage DC environments and pairs with compatible XL fuse bases and extraction tools.

• Rated for 1000V DC operation delivering high-voltage protection
• 250A current rating for high-current solar circuit protection
• Fast-acting characteristic enabling Rapid fault clearing
• High rupture capacity to interrupt severe PV fault currents
• Compatible with dedicated XL fuse bases and microswitches
• Minimal power loss under normal load to reduce thermal stress

• Suitable for protecting photovoltaic array combiners
• Ideal for inverter input and DC disconnect protection
• Used with multi-string solar installations prone to reverse current
• Can be used in industrial solar farms requiring HRC protection

The bolted variant uses a 2XL body pattern

A dedicated extraction handle sized for XL bodies is specified, and compatible microswitches can be fitted for electrical indication of fuse status.

Breaking capacity is defined per rated current and body size

The product family conforms to recognised IEC and UL photovoltaic fuse link standards and meets RoHS requirements.

Catalogue data lists compatible XL bases and microswitch part numbers for each body size and current rating to assist correct selection.
