Eaton 315A Tag Fuse 3L 1500V, 205 mm

This tag fuse provides protection for battery storage systems by interrupting fault currents in high-voltage DC environments. Designed for photovoltaic and energy storage installations, it is suitable for roles where Rapid disconnection and controlled interruption are required to safeguard string and battery modules. The device adheres to industry-standard performance criteria for protective links used in renewable and storage applications.

• 315A current rating delivers clear overcurrent interruption capability
• High-speed operation limits energy let-through during faults
• 1500V voltage rating supports high-voltage battery arrays
• 100kAIC breaking capacity handles severe short-circuit events
• 3L construction enables integration with standard 3-pole fuse holders
• Fixing centres set at 205mm simplify panel mounting arrangements

• Suitable for protection of high-voltage solar battery strings
• Ideal for battery energy storage system DC buses
• Used with inverter input protection in photovoltaic arrays
• Can be used for Rapid isolation in industrial storage racks

It is tested in accordance with IEC 60269-7, specifying performance for low-voltage DC protective devices in battery applications.

The overall length of 205mm allows predictable spacing in fuse carriers and matched clearance planning.

The unit measures 75mm across and 85mm high, informing enclosure cut-outs and adjacent component spacing.

The fixing centre dimension of 205mm provides the required datum for secure attachment and mechanical restraint.

Rapid operation reduces the duration of fault currents, thereby decreasing thermal and electrochemical stress on battery cells.
