Clearance requirements: 50 mm above, 32 mm in front, 10 mm at the sides and below, zero behind — plan the enclosure layout so the spring-loaded terminals are accessible for wiring. Spring-loaded terminals on both the main current circuit and the auxiliary/control circuit — no screw torque to verify, but the wire must be stripped to the correct length and fully inserted until the cage clicks. ## Supplied components and integration The reversing starter ships as a pre-assembled unit: the contactor is a 3RT2027-2BB40, the circuit breaker is a 3RV2021-4NA20, and the link module is 3RA2921-2AA00 — all S0 size, so the mechanical and electrical interlock is factory-set. An auxiliary switch extension is available (product extension auxiliary switch: Yes) — order the RH assembly kit 3RA2923-1BB2 if you need a spare or a different contact block configuration. ## Environmental and compliance Operating temperature range -20 to +60 °C; storage and transport range -50 to +80 °C — suitable for unheated warehouses and global shipping. RoHS compliance date 10/01/2009 — the part is RoHS-compliant per EU Directive 2011/65/EU.","metaTitle":"Siemens 3RA2220-4NF27-0BB4 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS 3RA2220-4NF27-0BB4 reversing starter, 15 kW at 400 V AC-3, Class 10, S0 size.
