Industrial terminal boxes provide a secure enclosure for terminal blocks, wiring junctions and small electrical components. The STB202012's IP66-rated steel construction helps isolate installed equipment from dust and water, reducing the risk of contamination-related component failure and unnecessary downtime.
The STB series is designed with practical installation features for machine builders and electrical engineers. Wall-fixing holes, internal mounting studs and dedicated earthing points make the enclosure straightforward to incorporate into industrial systems, while optional mounting plates and DIN profiles allow the internal arrangement to be configured for individual applications.
