Siemens SIRIUS Cage Clamp Technology

As an alternative to screw connections a large number of Siemens low voltage components are also available with cage clamp connections.,Solid, stranded and finely stranded conductors, with or without end sleeves, can be connected, where two conductors can be clamped independent of one another at each terminal.,Inserting a flat bladed screwdriver opens the terminal; the conductor is then introduced and securely clamped following the removal of the screwdriver. The chromium-nickel spring steel of the cage clamp terminal guarantees corrosion resistant contact of the conductors.

Time saving: the connection can be made quickly without having to press on end sleeves
Reliability: the terminal connection is resistant to shock and vibration
Vertical Mounting
Reduced maintenance: the cage clamp system means that the checking of screw connections following transportation is unnecessary
