Splicing Connectors for Ex Applications: The 221 Series Connects Easily, Quickly and Reliably

New Design Possibilities for Manufacturers of Junction Boxes, Luminaires and Electronic Devices for Ex Areas

Pull the lever up, insert a conductor and push the lever back down – done. Just in time for the major chemical industry trade shows, WAGO is presenting its electrician-trusted 221 Series as an all-purpose connector for hazardous areas. The new 221 Series for Ex applications carries type protection “e” for increased safety, opening up entirely new design possibilities for the manufacturers of junction boxes, terminal boxes, lights or electronic devices intended for hazardous areas in zones 1 and 2.

Your benefits:

  • Easy to use: Pull lever up, insert conductor and push lever back down

  • Connect fine-stranded conductors from 0.14 to 4 mm² (24–12 AWG)

  • Connect solid and stranded conductors from 0.2 to 4 mm² (24–12 AWG)

  • Mounting carrier for installation conforming to standards

  • Working voltages: 275 V or 440 V

  • ATEx: Ex II 2 G  / Zone 1, 2

  • IECEx, American Ex: Ex eb IIC T4 Gb / Class 1, Zone 1

Easy Termination for All Conductor Types

The connector’s lever can be easily opened by hand, the conductor inserted and the lever pushed back down. The new connectors accommodate fine-stranded conductors from 0.14 to 4 mm2, as well as solid and stranded conductors from 0.2 to 4 mm2 (24–12 AWG).

Fast and Secure Connection with the Mounting Carrier

The 2-, 3- and 5-wire connectors can be easily inserted into WAGO’s matching mounting carrier. The carrier fulfills the normative requirement for securing the clamping point. When the connectors are placed close together in the carrier, the working voltage is 275 V. For applications with working voltages up to 440 V, the connectors are inserted so that a spacer is visible between each connector. These spacers comply with the required clearances and creepage distances for working voltages up to 440 V in accordance with the standard.

The carrier can either be clamped onto a mounting rail or screwed tightly to any smooth surface. Even when the connector is already inserted into the carrier, conductors can be connected and disconnected, for example, when rewiring individual conductors – a decisive advantage for applications in Ex areas! This is because conventional distribution boxes for Ex applications are equipped with jacket clamps, which make it difficult to loosen individual conductors.

Certificates for ATEX (Ex 2 II G), IECEX and American Ex (AEx eb IIC T4 Gb) have been requested for international use of the WAGO 221 Series for Ex applications.

Expected to be available in autumn 2018, manufacturers can count on including WAGO’s connection technology in their new products for Ex areas.
