What this is and where it fits
The Siemens 3RV6928-0B is a push-in lug from the SIRIUS accessory range — a clip-on terminal adapter sized for the SIRIUS modular system. At a width of 10 mm, depth of 4.7 mm, and height of 27 mm, it adds a push-in wiring point directly onto the device bus or contactor base without taking up extra DIN-rail space. The clip-on fastening means it snaps onto the SIRIUS mounting rail or directly onto compatible SIRIUS devices, keeping the panel layout dense.
Temperature range and panel environment
Rated for operation from -20 °C to +70 °C, with storage tolerance from -50 °C to +80 °C. That operating span covers most indoor panel environments — heated control rooms, unheated warehouses, and the inside of a motor control center. The storage range is wide enough to handle transit through cold climates or hot containers without issue.
Mounting and wiring note
Clip-on fastening: no screws, no DIN-rail adapter needed — it snaps into place on the SIRIUS mounting profile or directly onto the device. The push-in lug accepts solid or ferruled stranded wire; strip length and wire gauge follow the SIRIUS accessory standard. Because the lug is only 10 mm wide, multiple units can sit side by side without crowding the termination point.
