R. STAHL introduces new, cost-efficient aluminium housings with Ex d ignition protection that protect standard industrial electrical components in hazardous areas. The 8250 series is designed for stand-alone wall installation and can be used in zone 1/21 or 2/22 hazardous areas (gas group IIB). At the moment, R. STAHL offers two models with internal dimensions of 250 x 150 x 110 mm and 300 x 230 x 125 mm. Three further models with internal dimensions up to 540 x 360 x 300 mm will follow until the end of the year. The spacious enclosures can accommodate motor starters with performances up to 45 kW and bulky control technology. While the flameproof enclosures are an economical solution to provide for safe use of the industrial components, the housings are still easily accessible for installation work and reconfigurations: the lids can be hinged at any side, open wider than 180°, and can be equipped with captive screws if required.
Electrical components can be mounted either directly on profile rails or on mounting plates. Through a CAD-optimised design, the housing’s weight was reduced by 15%. Moreover, its copper-free aluminium alloy also ensures exceptional robustness, allowing for use in different regions throughout the world. The material is seawater-resistant. Depending on the housing’s mechanical features, it will tolerate environmental temperatures between -60 °C and +70 °C. Rated IP66, the 8250 series is also dust-tight and withstands strong water jets. The new aluminium housings are available with or without drill holes and can be equipped with an optional powder coating.
