Eaton 400A Tag Fuse 217 x 82 x 94 mm 1500V, 205 mm

This tag fuse is designed for use in photovoltaic systems to protect DC circuits in solar installations. It operates at system voltages up to 1500V and offers a high current interrupting capability suitable for demanding PV arrays. The unit is intended for fast-response circuit protection where Rapid disconnection is required to limit fault energy and protect downstream components.

• 400A current rating delivers robust overcurrent protection
• Fast-acting characteristic minimises energy let-through during faults
• 100kAIC high rupture capability enables interruption of large fault currents
• High-speed operation supports Rapid isolation of defective string sections
• Fixing centres of 205mm allow straightforward panel mounting

• Suitable for string-level protection in large-scale solar farms
• Ideal for protection of in-field combiners and DC distribution boards
• Used for safeguarding high-voltage PV arrays up to 1500V
• Can be used for retrofitting older PV systems to higher voltage standards

It conforms to CSA, UL and IEC 60269 specifications, providing recognised test criteria for fuse performance in photovoltaic applications.

The fuse has an overall Compact footprint with key package dimensions of 217x82x94mm to assist panel designers in space planning.

It is designed with 205mm fixing centres to match common enclosure and rail layouts for Rapid installation.

The high-speed, fast-acting behaviour reduces fault duration, limiting thermal and mechanical stress on strings and inverters during short-circuit events.
