Siemens new Tandem Combination type AFCI circuit technology feeds two separate circuits from one breaker position. Twin AFCI breaker fits in new or existing construction and saves space in a loadcentre. Available in Pig Tail or Plug on Neutral versions.

The Plug on Neutral Breakers have a single load lug(s) only, wiring is made easier with the neutral lug removed. These breakers can be installed in the same manner as the thermal magnetic breakers in Siemens SNC loadcentres. This allows the installer to land ground and neutral conductors in the load center before installing the breaker and load conductor. The new design allows for the same reliable installation method using the neutral clip as the line side clip.
