NVENT HOFFMAN STB406012 Terminal box, 400x600x120

Why Choose the nVent HOFFMAN STB406012 Mild Steel Terminal Box?

The nVent HOFFMAN STB406012 is a robust mild steel terminal box designed to protect electrical terminals, cable connections and small control components in demanding industrial environments. Part of the nVent HOFFMAN STB terminal box series, it provides a practical enclosure solution for terminal blocks, junctions and auxiliary electrical equipment.

Manufactured from mild steel, the STB406012 combines durable industrial construction with a RAL 7035 light grey powder-coated finish. Its IP66 protection rating provides complete protection against dust and protection against powerful water jets, making it suitable for applications where dependable environmental protection is required.

Measuring 400 mm high × 600 mm wide × 120 mm deep, the STB406012 provides a generous internal area for larger terminal arrangements and associated wiring while retaining a relatively shallow enclosure profile. Its wide format makes it particularly suitable for rows of terminal blocks, cable junctions and electrical connections used in machinery, automation and industrial distribution systems.
