Viridian ARC04-12 ArcBox Solar Connector Enclosure – Fire-Resistant Safety Housing for DC PV Connections
The Viridian ARC04-12 ArcBox is a specialised enclosure designed to contain and isolate DC connector arcs in solar PV systems. Its patented design fully encloses the connector in a fire-resistant shell, preventing arc-related ignition on combustible surfaces. Independently tested by KIWA and Loughborough University, it is ideal for high-risk and high-consequence environments.
- Arc Containment Technology: Encloses DC connectors to prevent arc flash from igniting nearby combustible materials.
- High-Temperature Materials: Constructed from advanced refractory materials previously used only in crucibles and furnaces.
- Patented Snap-Fit Design: Two hinged halves snap together around the connector, suspended between sealing grommets for insulation and ventilation.
- Ventilated & Moisture Resistant: Integrated ports prevent moisture build-up and regulate operating temperature for connector safety.
- Ideal for Fire-Sensitive Installations: Recommended for BIPV, timber roofs, or other high-consequence locations.
