5SJ6…-.KS Miniature Circuit Breakers, with Plug-in-Terminals


Miniature circuit breakers with plug-in terminals are used for the protection of socket outlets and lighting circuits with the most common rated currents of 10 to 20 A.


  • Double, self-contained, screwless outgoing terminals for fast connection of conductors.

  • The plug-in terminals offer angled, easily accessible cable entries for manual insertion, which saves mounting time.

  • Separate removal of individual conductors requires no tools and ensures high operating safety.

  • No end sleeves required for finely stranded conductors. This saves mounting time.

  • Conventional pin busbars are used for the incoming terminal. This ensures clear, manageable and convenient access to all connections within the framework of the Siemens connection concept.
