In railway transportation, ship building, machinery and equipment applications: For many years, X-COM S has been used wherever time-saving system wiring is required. Approval for use in Zone 2 Ex area expands the range of applications for WAGO's pluggable S DIN-rail terminal block system. All X-COM S Carrier Terminal Blocks and Female Plugs, which are approved for Ex applications, are identified by the item number suffix ".../0999-0953". With a maximum wire size of 2.5 mm² (AWG 14), they are designed for a nominal current of 20 A. Compared to standard X-COM S components, the shorter locking lever, which is factory-mounted on the female plug, makes accidental disconnection even more difficult. Removing the female plugs is only possible using an operating tool, providing additional safety particularly for sensitive applications in hazardous areas. X-COM S for Ex applications will be available in 1- to 15-pole configurations in gray, blue and green-yellow. Each Ex module is subjected to a high voltage test during the manufacturing process. The modular design provides many possibilities to create custom female plug assemblies. Connectors can be prepared regardless of the final installation requirements and pre-assembled groups can be tested prior to installation. Groups having the same number of poles can be mechanically coded, preventing any mismating right from the beginning. This modular design significantly streamlines servicing even in Ex areas (e.g., offshore platforms). This not only saves time and money, but also allows assembly by external service providers and subcontractors.
