Reversing starter, size S0 — what ships inside
The 3RA2220-1FB24-0AP6 is a Siemens SIRIUS non-fused reversing motor starter, size S0, built around the 3RT2024-1AP60 contactor and the 3RA2921-1AA00 link module. Rated for AC-3 switching up to 690 V, this starter handles reversing duty on conveyors, hoists, and any load that needs forward/reverse control without an external interlock contactor pair.
Panel fit — DIN rail envelope and clearances
Snaps onto 35 mm standard rail per EN 60715; mounting position is vertical only. The body measures 120 mm deep by 90 mm wide by 265 mm tall — plan for 30 mm clearance above, 10 mm below, 10 mm forward, and 9 mm to the side for airflow and wiring access. Main power terminals accept 1 to 10 mm² stranded, or 2 × (2.5 to 6 mm²) — common for panel wiring with ring or fork lugs.
Environmental limits and compliance
Operates from -20 to +60 °C ambient; storage range is -50 to +80 °C, transport -55 to +80 °C. Pollution degree 3 rating means it's suitable for industrial environments with conductive dust or occasional condensation — standard for unsealed panel gear. Substance prohibitance date of 03/01/2017 aligns with RoHS compliance scope.
