Product details

The Siemens SIRIUS 3RA2225-4CB27-0AK6 is a non-fused reversing motor starter from the 3RA2 series, size S0. The supplied contactor is a 3RT2027-1AK60; the link module is 3RA2921-1AA00. The circuit-breaker size matches S0. This is a complete reversing starter package — wire it in and commission.

Clearance and panel fit

Snap-on fastening on 35 mm DIN rail, vertical mounting only. Required clearances: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards. That 0 mm backwards means it can sit flush against the back panel — useful when gland-plate depth is tight. Operating temperature range -20 to +60 °C; storage -50 to +80 °C; transport -55 to +80 °C.

Rated insulation voltage 690 V. AC-3 rated maximum voltage 690 V.

Frequently asked questions

What is the closest functional second-source for 3RA2225-4CB27-0AK6?

The 3RV2023-4CA10 is a circuit-breaker from the same SIRIUS S0 family, but it is a standalone motor-protective circuit-breaker, not a reversing starter. The 3RA2225-4CB27-0AK6 is a complete reversing starter assembly with contactor and overload relay; the 3RV2023-4CA10 would require separate contactors and a reversing contactor assembly to match function. They share the S0 frame size and DIN-rail footprint, so a panel designed for the 3RV2023-4CA10 could physically accept the 3RA2225-4CB27-0AK6, but wiring and control logic differ.
