Eaton 400A Tag Fuse 91 x 201.4 x 73.5 mm 1000V, 170 mm

This tag fuse is designed for protection within photovoltaic systems, providing overcurrent interruption for solar arrays operating at high DC potentials. It is intended for use where Rapid disconnection of fault currents is required to protect strings, inverters and downstream equipment in PV installations.

• 400A rating permits high-current PV string protection and system sising
• 1000V DC capability allows direct connection to high-voltage arrays
• High-speed operation limits energy let-through during faults
• 50kAIC high rupture capacity clears substantial fault currents
• Conforms to IEC60269 series for recognised electrical performance
• Fixing centres of 170mm simplify secure panel or rail mounting

• Suitable for mid-to-large rooftop solar string protection
• Ideal for use in commercial PV farm combiner panels
• Used with inverter input protection on high-voltage arrays
• Can be used for Rapid disconnection in solar maintenance procedures

The fuse requires 170mm between fixing points to align with enclosure or rail attachments.

The body measures 91 x 201.4 x 73.5 mm which aids dense layouts in combiner boxes.

The high-speed characteristic reduces fault duration and limits thermal and mechanical stress on conductors.
