Mounts on a 35 mm standard DIN rail via the supplied adapter, or directly with screws — the S0 size (265 mm high × 90 mm wide × 120 mm deep) fits a standard motor-starter slot in a Siemens SIRIUS feeder panel. The supplied contactor is a 3RT2027-1AP00, the circuit-breaker is a 3RV2021-4NA10, and the link module is a 3RA2921-1BA00 — the assembly is pre-configured as a reversing starter, so you don't need to source and wire the interlock separately. Clearance requirements: 50 mm above, 32 mm in front, 10 mm at the sides and below — plan the gland plate and cable ducts accordingly for airflow and access to the screw terminals. Rated for 50/60 Hz operation, 690 V maximum at AC-3, and the operating temperature range is -20 to +60 °C — suitable for most industrial control panels without derating for ambient.","metaTitle":"Siemens 3RA2220-4NB27-0AP0 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS reversing starter, 15 kW at 400 V AC-3, Class 10 thermal overload, S0 size.
