DESCRIPTION

The plug-in terminal strip 321-S is available in 10 mm pitch with 1 to 12 poles. It has one screw connection per pole and one vertical pin for the connection to the socket of the female counterpart. The plug-in terminal strip was designed with a solid pin in order provide permanent annular contact to the socket of 321-B. 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.
