NVENT HOFFMAN SSTB303012 Terminal box, 300x300x120

Why Choose the nVent HOFFMAN SSTB303012 Stainless Steel Terminal Box?

The nVent HOFFMAN SSTB303012 is a robust SSTB Series stainless steel terminal box designed to protect electrical terminals, connections and compact control components in demanding industrial environments. Manufactured from AISI 304L stainless steel, it provides excellent corrosion resistance for both indoor and outdoor electrical installations.

Measuring 300 × 300 × 120 mm (H × W × D), the SSTB303012 provides useful internal space for terminal blocks, wiring and associated components while retaining a compact square footprint. It offers IP66 ingress protection, Type 4X, 12 and 13 enclosure ratings and IK08 impact resistance, providing dependable environmental and mechanical protection.

The enclosure features a folded and seam-welded body manufactured from 1 mm stainless steel with a 1.5 mm cover and a 400 pre-grained finish. Four internal M6 × 13 mm studs accommodate compatible mounting accessories, while M8 × 18 mm earthing studs in the body and cover support protective bonding within the finished installation.
