Overview

The nVent SSTB303008-316 is a 300x300x80mm stainless steel 316 terminal box designed for harsh industrial environments. This enclosure provides IP66 protection against dust and water ingress, making it suitable for both indoor and outdoor applications where corrosion resistance is critical. Constructed from 1mm-thick AISI 316L stainless steel with a brushed finish, the SSTB303008-316 offers superior resistance to pitting and crevice corrosion in saline or chemically aggressive environments. The enclosure features a polyurethane gasket for reliable sealing, M8x18mm earthing studs in both body and cover, and laser-marked back corners for precise mounting bracket placement. With a depth of 80mm, this terminal box provides ample space for terminal blocks and wiring while maintaining a compact footprint. The brushed stainless steel finish ensures durability and a professional appearance. Ideal for chemical processing, marine, food and beverage, and wastewater treatment facilities, this terminal box eliminates the risk of component failure due to environmental ingress, reducing costly downtime.
  • Material: AISI 304L pre-grained stainless steel / AISI 316L (on request). Body: 1 mm. Cover: 1.5 mm.
  • Body: Folded and seam welded. Four M6x13 studs for bottom profile / mounting plate fixation. For ease of installation, each back corner of the enclosure is laser-marked to precisely indicate where to drill holes and affix AWS wall mounting brackets.
  • Gasket: Sealing is ensured by an injected polyurethane gasket. For AISI 316L, sealing is ensured by an injected silicone gasket.

How to Safely Mount SSTB303008-316 Equipment

This guide provides essential safety instructions for mounting the SSTB303008-316, particularly concerning combustible surfaces and maintaining enclosure integrity.

Estimated time: 15m

Tools needed:

Measuring tape, Basic hand tools

Supplies needed:

Galvanized steel floor plate (if needed), Uncoated steel floor plate (if needed), Compatible enclosure closing devices

  1. Assess Mounting Surface and Prepare for Combustible Materials

    Before mounting the SSTB303008-316, evaluate if the surface is combustible. If it is, install a floor plate made of at least 1.43 mm galvanized steel or 1.6 mm uncoated steel. Ensure this plate extends a minimum of 150 mm beyond the equipment on all sides to comply with safety regulations.

  2. Mount the SSTB303008-316 Equipment Securely

    Carefully position the SSTB303008-316 equipment on the prepared surface or directly onto a non-combustible surface. Securely fasten the equipment using appropriate mounting hardware, ensuring it is stable and firmly attached.

  3. Ensure Enclosure Environmental Integrity During Customization

    If customizing the enclosure or closing any openings, use only devices that possess the same environmental ratings as the SSTB303008-316 enclosure. This critical step prevents degradation of the equipment's environmental protection.
