The 24 V control voltage matches common PLC or relay outputs, and the Trip Class 10 protection means it trips within 10 seconds at 7.2× the set current, standard for general-purpose motor starting. Rated for AC-3 switching up to 690 V, this starter handles reversing duty on motors up to 550 W at 400 V and 1.1 kW at 690 V. The thermal overload is adjustable via a bimetallic element — no electronic settings to lose on power loss. The size S0 footprint (130 mm deep, 90 mm wide, 265 mm high) fits standard panel layouts, and the snap-on rail mount means no tools for installation. Snaps onto 35 mm standard rail, mounted vertically. The supplied contactor (3RT2023-1BB40) and link module (3RA2921-1BA00) are pre-assembled; the busbar adapter (3RA2922-1AA00) is included for line-side connection. Main terminals accept 1–10 mm² stranded or 2×(2.5–6 mm²).","metaTitle":"Siemens 3RA2225-1AB23-0BB4 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA2225-1AB23-0BB4 SIRIUS reversing starter, non-fused, size S0, Trip Class 10, 24 V control, 690 V AC-3 max.
