What this compact starter handles
The 3RA6120-2DP32: The trip class is field-adjustable between CLASS 10 and CLASS 20, so you match the thermal curve to the motor start profile — CLASS 10 for shorter acceleration times, CLASS 20 for high-inertia loads like fans or conveyors that take longer to come up to speed.
Coil supply and wiring
The coil accepts 110-240 V AC/DC across 50 and 60 Hz — one part number covers both line frequencies and DC control supplies, so you don't need to track separate coil variants. Power consumption is 6 W AC and 5.1 W DC, which keeps the heat rise low inside a crowded panel. Two integrated status LEDs give a quick visual on coil state and overload trip without needing a multimeter. Main circuit connections use spring-loaded terminals accepting solid wire 2x 0.25-1.5 mm² — no screw torque to check, just strip and push. The control circuit terminals are likely the same spring-clamp style (common on SIRIUS compact starters), though the evidence only confirms the main circuit termination.
Mounting and environment
Mounts by screw or snap-on onto standard DIN rail, with recommended vertical orientation on horizontal rail — though the unit itself can be installed in any position. Rated for pollution degree 3 — that's industrial environments with conductive dust or condensation, so no extra conformal coating needed for most panel environments. Operating temperature range is -20 to +60 °C, storage and transport -55 to +80 °C. Vibration resistance is tested to 20 m/s² at 5.8-500 Hz, and shock resistance to 60 m/s² (6g) for 10 ms — rated for machine-mounted applications where the panel sees regular vibration from nearby motors or presses.
