The TE5S timer provides the star coupling time delay and manages a lapse of 50 ms before triangle switching. An output relay with changeover contact provides high current switching. A two-position changeover switch selects one of the two time-delays: 0.8 → 8 s or 6 → 60 s. Button marked 0.1 → 1 is used for setting within the pre-selected range. DIN rail assembly. For A series switches. Two voltages available.
