Eaton releases  explosion-protected Ex-wall sockets

December 1, 2014 - Eaton Crouse-Hinds division releases explosion-protected Ex-wall sockets that prevent fault tripping as a result of long cable lengths, reduces distances to the protective device if it trips, and allows the equipment to be switched on again quickly once the fault has been eliminated.

The Ex-wall sockets have integrated RCD/MCB (RCBO) protection,  an IP66 plastic (GRP) enclosure and are suitable for installation in hazardous gas areas (Zone 1 & 2) and hazardous dust areas (Zone 21 & 22).

For extra protection in hazardous gas and hazardous dust environments, explosion-protected wall sockets can be fitted with local protection devices in the form of a Residual Current Circuit Breaker (RCD) or Miniature Current Circuit Breaker (MCB). In the event of a fault with the connected equipment, the function of the RCD/MCB socket is to protect personnel from serious injuries due to electric shocks. With a built-in protection device, the feed line and the end unit can be protected individually to suit the required load. Individual work areas can be isolated while maintenance is carried out. In the event of a fault, only the area affected is switched off – all other areas remain fully functional. Individual areas can also be switched off manually and safeguarded from being switched on accidentally by using a safety padlock.

The integrated RCD/MCB protection devices can be accessed easily at any time by using the actuating flap/cover. With a tripping current of 10-500mA, in the event of a fault with the connected equipment, the RCD/MCB device protects personnel from serious injuries due to electric shocks.

The Ex-wall sockets are available in three enclosure sizes with rated currents of 16A and 32A and rated voltages from 24V up to 400V. Permissible ambient temperatures are from -20°C to +40°C.

 

As Franz Ruscher, Product Line Manager Connectivity, Eaton’s Crouse-Hinds Business states: “The design of the Ex-wall sockets with RCD/MCB protection is based on our tried-and-tested enclosure series, combined with our robust flange sockets and built-in Ex-components, so customers can rest assured they are installing a high quality, robust, reliable wall socket with a high degree of protection.”

He continues: “The protection device will not trip, even if cable lengths are long. By placing the RCCB/MCCB directly in the wall socket, cable lengths are reduced and faults minimised. The Ex-wall sockets also allow direct, on-site access to the safety devices. This means that users can react more flexibly with reaction and equipment restart times reduced significantly.”

Eaton’s Crouse-Hinds division offers a range of cable fittings, enclosures, plugs and receptacles, industrial lighting fixtures, signals and alarms, and electronic components designed for the most demanding environments. The Crouse-Hinds business serves customers in the industrial and manufacturing, mining, oil and gas, solar, infrastructure and other markets.
