NVENT HOFFMAN STB408012 Terminal box, 400x800x120

Why Choose the nVent HOFFMAN STB408012 Terminal Box?

The nVent HOFFMAN STB408012 is a robust mild steel terminal box designed to protect electrical terminals, wiring and control components in demanding industrial environments. As part of the nVent HOFFMAN STB terminal box series, it provides a secure enclosure solution for electrical distribution, automation and machine-building applications where dependable environmental protection is required.

The enclosure is manufactured from durable mild steel with a folded and seam-welded body for mechanical strength. An injected one-piece polyurethane gasket provides effective sealing between the enclosure body and cover, helping the STB408012 achieve its IP66 protection rating against dust and powerful water jets. A structured RAL 7035 powder-coated finish provides a durable and professional surface for industrial installations.

With dimensions of 400 mm high × 800 mm wide × 120 mm deep, the STB408012 provides substantial internal width for arranging terminal blocks, wiring and associated electrical components while maintaining a relatively shallow enclosure profile. Integrated mounting and earthing provisions simplify installation and help make the enclosure suitable for a wide range of industrial electrical systems.
