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
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.
