What it is and where it fits
The Siemens 3RT1955-4NQ02 is a 2-pole connection plug designed for the electronic drive contactor series 3RT1.5* through 3RT1.7*. It belongs to the solenoid coils product family and serves as the wiring interface between the control circuit and the coil on those contactor frames. The plug snaps onto the contactor's coil terminals, providing a standardized 2-pole connection point. This avoids hard-wiring directly to the coil spade terminals, which simplifies replacement and maintenance on the contactor.
