Why Choose the nVent HOFFMAN SSTB304012-316 Stainless Steel Terminal Box?
The nVent HOFFMAN SSTB304012-316 is a robust SSTB Series stainless steel terminal box designed to protect electrical terminals, junctions and compact control components in demanding industrial environments. Manufactured from corrosion-resistant AISI 316L stainless steel, this version is particularly suited to applications where enhanced resistance to moisture and corrosive conditions is required.
Measuring 300 × 400 × 120 mm (H × W × D), the SSTB304012-316 provides useful internal capacity for terminal blocks, wiring and associated electrical components. It offers IP66 ingress protection, Type 4X, 12 and 13 enclosure protection and IK08 impact resistance, helping protect installed equipment against dust, water and mechanical impacts.
The enclosure features a folded and seam-welded body, a durable 400 pre-grained stainless steel finish and an injected one-piece silicone gasket specifically used with the 316L version. Four internal M6 × 13 mm studs support compatible mounting plates or bottom profiles, while M8 × 18 mm earthing studs in the body and cover provide dedicated protective bonding points.
Key Advantages
- Enhanced corrosion resistance from AISI 316L stainless steel construction.

316L Stainless Steel Protection for Electrical Connections
The nVent HOFFMAN SSTB304012-316 provides a protected environment for terminal blocks, junction connections, sensors and compact electrical components. Its AISI 316L stainless steel construction offers enhanced corrosion resistance, while IP66 protection helps prevent dust and powerful water jets from reaching correctly installed internal equipment.
The 400 mm width and 120 mm depth provide useful space for terminal rows, cable routing and connection equipment without requiring a large enclosure footprint. Four internal mounting studs allow compatible mounting plates or profiles to be installed separately, while the silicone gasket and dedicated earthing provisions support reliable use across demanding industrial installations.
Typical Applications
- Industrial terminal and junction connections.
- Machine and equipment wiring.
- Process control and instrumentation systems.
- Automation, sensor and actuator connections.
- Indoor and outdoor industrial electrical installations.
- Applications requiring enhanced 316L stainless steel corrosion resistance.
