Eaton Tag Fuse, 400A Current, 1000V Voltage - BSF-400G-NH310


This tag fuse is a battery-storage protection device designed to interrupt fault currents in battery arrays and to isolate combiners and disconnectors. It operates at high direct voltage and is intended for use where fast interruption of reverse currents and multi-array faults is required in industrial electrical installations.

Features & Benefits


• Rated for 1000V DC operation for high-voltage battery systems
• 400A current rating for high-current battery protection
• Fast-acting characteristic reduces energy let-through during faults
• High rupture capacity enables interruption of large fault currents
• Compatible with NH3 bases for straightforward fitting
• Dual indicator and multiple fixing options simplify maintenance

Applications


• Suitable for protecting battery array combiners in storage systems
• Ideal for disconnecting battery banks in renewable energy plant
• Used with NH fuse bases in commercial energy storage installations
• Can be used for safeguarding multi-string battery racks

What breaking capability can be expected for heavy faults?


The fuse link is specified with a breaking capacity adequate for severe prospective currents, with a Peak interrupting capability matched to high-energy battery system faults.

Can microswitches or holders be fitted for remote monitoring?


The bladed version accepts specified microswitches and dedicated fuse holders to enable electrical position signalling and simplified integration into control systems.

How does time-response behaviour support system protection?


The fuse exhibits a Rapid pre-arcing time for high prospective currents while providing coordinated time to current characteristics across NH1 to NH3 sizes for selective clearing.

What packaging and ordering format is used for distribution?


Units are supplied in packs of three and are available with either knife-blade or bolted-blade terminations to match installation preferences.
