Eaton 400A Tag Fuse 3L 1500V

This tag fuse is a photovoltaic protective link designed to isolate and interrupt fault currents in solar array combiners and disconnects. It operates at high DC voltage for PV installations and is intended for use where Rapid disconnection of reverse or multi‑array fault currents is required. The product is compatible with dedicated PV fuse bases and can be specified for systems needing elevated DC voltage capability.

• Rated for 1500V DC operation providing extended system voltage capability
• 400A current rating enabling high‑current PV strings protection
• Fast‑acting characteristic for Rapid clearance of low overcurrents
• High rupture capacity to safely interrupt substantial fault energy
• Tag‑style construction for straightforward Visual identification
• Overall length 217mm for consistent panel integration

• Suitable for protecting photovoltaic array combiners in large‑scale installations
• Ideal for DC disconnects on rooftop and ground‑mount solar systems
• used with compatible XL PV fuse bases in inverter and combiner panels
• Can be used for isolation of multi‑string array faults in commercial systems

The fuse offers a high rupture capacity enabling interruption of significant fault energies at PV voltages, with testing performed to IEC and UL PV standards for photovoltaic use.

The tag format and specified overall length aid repeatable mounting and dimensional consistency within combiner and inverter layouts.

Its fast‑acting characteristic clears low overcurrent events quickly, limiting energy let‑through and reducing stress on downstream components.

The device is compatible with bladed and bolted base configurations and mates with designated XL PV bases and microswitch accessories for signalling.
