Eaton 350A Tag Fuse 217 x 82 x 94 mm 1000V, 170 mm

This tag fuse provides overcurrent protection specifically for photovoltaic systems, designed to interrupt fault currents in solar installations and safeguard downstream equipment. It operates within high-voltage PV arrays and is intended for integration into string-level protection schemes where fast disconnection under fault conditions is required.

• 350A continuous rating gives high current-handling capacity
• 1000V system compatibility supports medium-voltage PV strings
• High-speed operation reduces energy let-through during faults
• 50kAIC rupture capacity limits destructive fault energy
• 170mm fixing centres enable straightforward panel mounting
• Compact body dimensions ensure efficient enclosure space usage

• Suitable for protecting PV string combiner boxes in large arrays
• Ideal for commercial rooftop solar installations with 1000V systems
• Used with inverter input protection to prevent backfeed damage
• Can be used for maintenance isolation in photovoltaic maintenance panels

The device withstands and interrupts high prospective currents up to a 50kAIC rating, limiting thermal and mechanical stress on connected components.

The unit presents a Compact footprint of 75 x 91 x 205 mm overall with a height of 82mm and a width of 94mm to fit standard fuse holders and enclosures.

Mounting is facilitated by fixing centres set at 170mm to match common panel layouts and mounting brackets.
