Eaton 350A Tag Fuse 75 mm x 91 mm x 205 mm 1500V, 205 mm

This tag fuse is designed for protecting photovoltaic strings and related DC circuits in high-voltage solar installations. It functions as a fast-acting protective element for systems operating up to 1500 V, offering Rapid interruption of fault currents in utility-scale and commercial PV arrays while conforming to recognised international standards.

• 350 A rating delivers high-current protection for PV strings
• High-speed operation minimises energy let-through during faults
• 100 kAIC rupture capacity copes with substantial short-circuit currents
• Fast-acting characteristic reduces risk of inverter and string damage
• Tag-style format allows direct identification and manual handling

• Suitable for string-level protection on large photovoltaic farms
• Ideal for DC combiner boxes in commercial solar installations
• Used with array disconnects and isolation devices in plant rooms
• Can be used for protective segregation between parallel strings

It meets CSA, UL and IEC 60269 requirements, enabling use across multiple regulatory regimes.

The fixing centres are 205 mm to match holders designed for tag-format fuses.

The unit is a Compact Block with a footprint of 75 x 91 x 205 mm and a tag width of 91 mm.

Its attributes suit high-voltage, high-current DC applications where Rapid clearing and large rupture capacity are required.
