The Siemens 3RT2916-1GA00-ZX90 is a SIRIUS plug-in additional load module sized for S00 contactors, carrying an AC coil rated 180-255V at 50 Hz and 255-180V at 60 Hz. Clip-on mounting to the contactor front adds a load switching path without expanding DIN-rail footprint — the 9mm depth keeps the assembly within the contactor's own envelope.
At 28mm wide and 46mm tall, this module mirrors the S00 contactor face and clips on without tools. Mounting position is unrestricted, so vertical or horizontal rail layouts work equally. The 9mm depth projection means it stays clear of adjacent devices on the same DIN rail — no additional side clearance needed beyond the contactor's own.
Coil voltage and temperature range
The AC coil accepts 180-255V at 50 Hz and 255-180V at 60 Hz — note the reversed order on 60 Hz reflects the standard operating band for that frequency.
