Product details

Spring-loaded termination and wire sizing

The 3RA6912-2A: Stripped length is 10 mm. AWG equivalents for the auxiliary contacts are 2x (24... 14). The spring-cage grip holds the conductor without retightening, suited for panel wiring where vibration is present.

DIN-rail footprint and environmental limits

The switch occupies 45 mm width, 32 mm height, and 25 mm depth — a compact footprint that fits alongside SIRIUS feeder modules on standard DIN rail. Operating temperature range is -20... +60 °C with 10... 90 % relative humidity; storage and transport range is -55... +80 °C.
