Eaton 125A Tag Fuse 1XL 1500V, 159 mm

This tag fuse is designed for use in solar-power installations to provide overcurrent protection within photovoltaic arrays. It operates at elevated system voltages typical of modern PV setups and is intended for integration into fuse-holders where Rapid interruption of fault currents is required.

• 125A rating enables protection for higher-current PV strings
• 1500V capability supports long string voltages in utility-scale systems
• High-speed operation reduces energy let-through during faults
• 30kAIC interruption capacity mitigates large fault currents
• L-size form factor suits standard PV fuse holders
• 159mm fixing centres ensure consistent panel mounting alignment

• Suitable for protection of rooftop and ground-mounted solar arrays
• Ideal for string-level protection in commercial PV installations
• Used with DC fuse-holders in inverter input circuits
• Can be used for retrofitting older PV systems to higher-voltage architectures

It interrupts faults with a rated breaking capacity of 30kAIC to limit downstream stress.

The fixing centres measure 159mm to match compatible mounting fixtures.

The overall footprint includes an L-size fuse body with a length of 205mm and a height of 60mm.

Its width is 80mm, permitting close spacing within designated fuse assemblies.
