Product details

Reversing starter, complete — what ships in the carton

The 3RA2225-4CB27-0AP6 is a SIRIUS non-fused reversing motor starter from the 3RA2 series, Size S0. It ships as a factory-assembled unit with the contactor (3RT2027-1AP60) and link module (3RA2921-1AA00) already integrated — no separate kitting required for the reversing pair.

DIN rail fit and panel clearances

Snap-on mounting to a 35 mm standard rail, vertical position only. The enclosure footprint is 90 mm wide by 265 mm tall by 120 mm deep — a compact S0 package that fits a 200 mm deep enclosure with room for the wiring tray behind it. Clearance requirements: 30 mm above, 10 mm below, 10 mm in front, 9 mm to the side, and zero behind the unit. That 9 mm side gap is tight — adjacent starters or contactors need that space for heat dissipation and arc-chamber venting. No clearance needed at the back means you can push the rail against the back panel.

Ratings across the voltage range

The 50 Hz coil range is 176-242 V; the 60 Hz range is 192-264 V — covers 200-240 V line supplies globally. Pollution degree 3 means it's rated for industrial environments with conductive dust or occasional condensation — no derating needed for typical panel conditions.
