The nVent HOFFMAN SSTB203012 is a robust SSTB Series stainless steel terminal box designed to protect electrical terminals, connections and compact control components in demanding indoor and outdoor environments. Manufactured from corrosion-resistant AISI 304L stainless steel, it provides a durable solution for industrial installations where reliable protection against dust, water and corrosion is required.
Measuring 200 × 300 × 120 mm (H × W × D), the SSTB203012 combines useful internal capacity with a compact enclosure format. It provides IP66 ingress protection, Type 4X, 12 and 13 ratings and IK08 impact resistance, helping safeguard installed components against environmental and mechanical influences.
The enclosure features a folded and seam-welded body, a 400 pre-grained brushed stainless steel finish and an injected sealing gasket. Four internal M6 × 13 mm studs support the installation of compatible bottom profiles or mounting plates, while dedicated earthing studs in both the body and cover support protective bonding.
The nVent HOFFMAN SSTB203012 provides a protected environment for terminal blocks, junction connections, sensors and compact electrical components. Its AISI 304L stainless steel construction and IP66 protection make it suitable for applications where dust, moisture and environmental exposure could otherwise contribute to component failure and unnecessary downtime.
Four internal mounting studs provide flexibility for fitting a compatible mounting plate or bottom profile, while DIN rail arrangements can be added using separately available SSTB accessories. The 120 mm depth provides useful room for terminals and cable routing, and earthing facilities in both the body and cover support safe integration into industrial electrical systems.
