What It Is
The Siemens 3RT1916-4MA00 is a dust cover with a cage-clamp terminal design, packaged as a 150-piece lot for the S00 contactor frame size.
Where It Fits
This cover snaps onto the S00 contactor body, protecting the coil terminals and wiring from dust ingress in panel environments. The cage-clamp style accepts solid or ferruled stranded conductors — strip length and wire gauge follow the contactor's terminal spec.
