Marechal DXN Ex Decontactor range

The ATEX-approved, explosion-proof DXN Ex Decontactor range replaces a socket, a switch and a disconnector. One simple press of a button disconnects the current and prevents any risk of arcing. The plug contacts automatically retract, safely isolating plant and equipment from the load, and a safety shutter prevents any access to live parts.

Designed for explosive atmospheres, the DXN products conform, in full, to all leading national and international standards, are certified according to IEC Ex and comply with ATEX directive 94/9/EC for use in Zones 1 and 2 (gas) and Zones 21 and 22 (dust). They are suitable for use in hazardous areas where flammable gases, vapours or dust are likely to be present in the environment, such as can occur in the chemical, petrochemical, pharmaceutical and food industries.

Silver nickel butt contacts provide added reliability and longer life, and the IP66/IP67 watertight seal provides resistance to high-pressure washing. Other features include integral breaking capacity, compact and robust design and high-impact resistant polyamide casing. In addition, the spring-assisted terminals are unaffected by vibration and thermal cycling and the unique keying system allows discrimination between 24 different power supplies.

The DXN Ex Decontactor range is available from 20 A, 550 V, up to 63 A, 750 V. Versions with two auxiliaries (DXN3: 32 A, 550 V; DXN6: 63 A, 550 V) are also available.
