AC-3 rating and trip class — the fit for motor starting
The 3RA2120-1GD24-0FB4: The 24 V DC coil (24... 24 V rated value) keeps control voltage low for PLC-driven circuits.
Mounting and supplied components — what arrives in the assembly
This starter is designed for snapping onto 60 mm busbar systems, not standard DIN rail — the fastening method and product design both specify 60 mm busbars. Mounting position is vertical. The assembly ships with a 3RT2024-1FB40 contactor and a 3RA2921-1BA00 link module pre-integrated; the circuit-breaker portion is size S00. Envelope dimensions are 165 mm deep, 45 mm wide, 260 mm high. Clearance requirements: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side.
The lifecycle stage is marked as current — this is an active-production SIRIUS starter, not a legacy or phase-out line. Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. No PROFIsafe or PROFINET IO protocol support on this variant — it is a conventional hardwired starter.
