The 3RA2120-0GA23-0AK6: The supplied contactor 3RT2023-1AK60 and circuit breaker 3RV2011-0GA10 are matched at the factory — the coordination between the thermal overload (bimetallic) and magnetic short-circuit trip is pre-validated, so you skip the selectivity study for this branch.
DIN rail footprint and clearance — panel layout constraints
Snap-mounted to DIN rail or screw-mounted with a push-in lug — the 45 mm width and 97.1 mm depth fit a standard S0 feeder slot, and the 193.1 mm height leaves room for the busbar stack above. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, and 9 mm at the side — these are the minimum air gaps to maintain the rated insulation voltage of 690 V and pollution degree 3, not optional for the 6 kV surge withstand. Mounting position must be vertical — horizontal orientation shifts the bimetallic trip curve and voids the Class 10 timing guarantee.
Coil voltage and operating range — control circuit compatibility
The coil accepts 88–121 V at 50 Hz and 96–132 V at 60 Hz — a standard 110–120 V control transformer covers both frequencies without a separate tap change. Operating frequency is 50–60 Hz, so the starter works on 50 Hz or 60 Hz supply without derating the motor power ratings listed at 400 V, 500 V, or 690 V. The auxiliary switch extension is available — the product extension auxiliary switch flag is set to Yes, meaning the side-mount auxiliary contact block can be added without modifying the main assembly.
No pin-compatible alternative exists within the SIRIUS 3RA2 family for this exact voltage and power combination — the factory-matched contactor and breaker are specific to this order code.
