Reversing motor starter, size S0, CLASS 10
The 3RA2220-1EB23-0AP6 is a Siemens SIRIUS non-fused reversing motor starter in size S0, designed for snap-on mounting on a 35 mm standard DIN rail in a vertical position. Rated at 690 V (AC-3 maximum), this reversing starter handles motor switching up to that voltage level, with the supplied contactor 3RT2023-1AP60 and link module 3RA2921-1AA00 included in the assembly.
Panel space and mounting clearances
Dimensions: 120 mm depth, 90 mm width, 265 mm height — the S0 footprint fits standard motor-starter slots on a 35 mm DIN rail. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards — plan for these gaps around the device to maintain airflow and wiring access.
Environmental limits and compliance
Operating temperature range is -20 to +60 °C; storage tolerance -50 to +80 °C; transport range -55 to +80 °C — suitable for most industrial enclosures without active cooling. Degree of pollution 3 per IEC 60947-1, meaning the starter is designed for conductive pollution environments typical in industrial panels. RoHS compliance date (substance prohibitance) is 03/01/2017, confirming the part meets current substance restrictions.
