The 97 x 27 x 105 mm package fits a standard DIN-rail footprint. The wide control voltage range (24-230 V AC) simplifies panel wiring by covering both 24 V control circuits and 110-230 V line-voltage control without a separate transformer tap.
The product family (SIRIUS 3RF33) is Siemens' compact solid-state contactor line, positioned for resistive heating, lamp, and transformer loads where silent, wear-free switching is needed.
