RS PRO ST Series Steel Junction Box Grey 200 x 200 x 80 mm IP66 IECEx - IP66

The RS PRO IP66 ST Series Steel Junction Box is crafted to meet the rigorous demands of industrial, commercial, and construction environments requiring reliable protection of sensitive electrical connections. Manufactured from robust 1.5 mm thick steel and finished in RAL 7032 grey, this junction box offers long-term resistance to mechanical stress, corrosion, and environmental hazards. Its rugged all-welded body ensures mechanical stability, while the included wall brackets, made from 2.6 mm steel, provide secure installation on flat surfaces for versatile mounting options.

With an ingress protection rating of IP66, the enclosure protects against jetting water, dust, and moisture infiltration, making it suitable for deployment in both indoor and outdoor applications such as manufacturing lines, control panels, process automation equipment, and building infrastructure. The fitted black polyurethane seal gasket within the lid compresses effectively against all-round knife edges to maintain its high IP rating over extended usage - ideal for sites subject to rigorous cleaning, rain, or airborne particulates.

Measuring 200 mm by 200 mm with an 80 mm depth, the junction box provides ample enclosed space for wire terminations, DIN rail accessories, or small circuit assemblies. The design omits knockouts or pre-installed terminals, allowing engineers to customize cable entry and internal layout as per unique project requirements. Despite the compact form, the interior is optimized for straightforward layout and easy access during circuit modifications or maintenance.

RS PRO has engineered this terminal box to meet strict industry standards, with RoHS compliance ensuring minimal environmental impact and IECEx hazardous area certification supporting installation where dust, gas, or chemical exposure is a concern. Typical use cases extend from electrical circuit protection and distribution in factories, workshops, and HVAC machinery to applications such as extending or repairing electrical circuits, additional socket or lighting point connections, and integrating site automation infrastructure.

The junction box's strength, ingress protection, and certified construction make it a preferred choice for OEMs, electrical contractors, and facilities managers seeking long lifecycle components. Not supplied with a flange, DIN rail, or chassis plates, the box offers a blank canvas for project-specific configuration. Maintenance-friendly features, such as easy-opening covers and robust corrosion resistance, further support its industrial deployment.
