ATEX Detectors, Control & Distribution Units Zone 1 & Zone 2 Control Station Weatherproof Ex d – Eaton MEDC GHG 432 & 434

Eaton MEDC GHG 432 & 434 are ATEX control & distribution junction boxes intended for use in potentially explosive atmospheres in ATEX & IECEx Zone 1 and Zone 2 hazardous areas – suitable for use in all gas groups including hydrogen. (Except Acetylene Class I, Zone 1)

These control & distribution stations are manufactured from a UV stable, impact resistant polyamide; cover fixing screws are stainless steel thus ensuring a corrosion-free product.

The GHG 432 & 434 ranges are 2 and 4 way units with larger termination area for heavy duty offshore cable.

The high ingress protection rating makes this range of control stations suitable for use in harsh environmental conditions.
