Explosion-proof GHG command devices made of aluminium-silicon alloy
Explosion-proof GHG command devices made of aluminium-silicon alloy
The GHG explosion-protected command devices with light alloy housing can be equipped with up to 4 components. The housings of these explosion-proof command devices are made of high-grade aluminium-silicon alloy (AlSi).
Cover screws and other external and internal parts are made of stainless steel. Explosion-protected CEAG recessed parts, signal lamps, pushbuttons and switches, snap onto the mounting rail. To facilitate the insertion of cables into the cable glands, the recessed components can be snapped into place.
The slots in the mounting rail define the position of the embedded components and prevent them from being installed incorrectly. Free mounting fields can be used for mounting modernised and certified component parts. Unused holes and openings are closed at the factory with plugs.
