321-B(-DS)Plug-in terminal strip Screw connection & socket 03.19WECO | www.wecogroup.com The plug-in terminal strip 321-B is available in 10 mm pitch with 1 to 12 poles. It has one screw connection per pole and one plug connection for a terminal strip with pins. The special moulding houses a spring-loaded terminal body with six slots and is protected against accidental contact. A funnel guides the solid male plug 321-S. This combination provides permanent annular contact. The wire protector of the “DS”-version reliably prevents damage to multi-wire flexible conductors by the turning screw. These terminals strips can be screw-mounted on a substrate.
