NVENT HOFFMAN SSTB306012 Terminal box, 300x600x120

Why Choose the nVent HOFFMAN SSTB306012 Stainless Steel Terminal Box?

The nVent HOFFMAN SSTB306012 is a robust AISI 304L stainless steel terminal box designed to protect electrical terminals, cable connections and small control components in demanding industrial environments. Part of the nVent HOFFMAN SSTB stainless steel terminal box series, it combines corrosion-resistant construction with a practical screw-fixed cover for dependable indoor and outdoor equipment protection.

With an IP66 protection rating and IK08 impact resistance, the SSTB306012 provides effective protection against dust, powerful water jets and mechanical impacts. Its body is manufactured from 1 mm AISI 304L stainless steel, while the cover uses 1.5 mm stainless steel, providing a durable enclosure for industrial terminal and junction applications.

Measuring 300 mm high × 600 mm wide × 120 mm deep, the SSTB306012 offers a wide internal area suitable for rows of terminal blocks and associated wiring while retaining a relatively shallow profile. Its 400 pre-grained brushed stainless steel finish, seam-welded body, integrated mounting studs and earthing facilities make it a practical choice for industrial automation, machinery and process installations.

Reliable Protection for Electrical Terminations

Industrial terminal boxes provide a secure location for terminal blocks, cable junctions and electrical connections while protecting installed components against environmental conditions. The IP66-rated nVent HOFFMAN SSTB306012 helps prevent water and dust from entering the enclosure, reducing the risk of electrical component failure and unnecessary equipment downtime.

The AISI 304L stainless steel construction provides excellent corrosion resistance for indoor and outdoor industrial applications. Its 600 mm width and 300 mm height provide useful space for larger terminal arrangements, while the relatively shallow 120 mm depth helps maintain a space-efficient installation. A compatible BMP3060 mounting plate can be ordered separately when required.

Typical Applications

• Electrical terminal block installations.
• Industrial cable junctions and connections.
• Machine control and automation systems.
• Process control and instrumentation equipment.
• Indoor and outdoor industrial electrical installations.
• Manufacturing and production machinery.
• Electrical distribution and auxiliary circuits.
• Applications requiring corrosion-resistant stainless steel protection.
