Eaton 350A Tag Fuse 75 mm x 91 mm x 205 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.
