Reversing starter that fits a tight panel slot
The 3RA2225-1AB23-0AK6 is a SIRIUS 3RA2 non-fused reversing motor starter in size S0 — meaning the contactor, overload relay, and reversing interlock ship as a single DIN-rail unit, not a field-assembled stack. Snap-on mounting on 35 mm standard rail, vertical position only — the thermal bimetallic overload (CLASS 10 trip class) is calibrated for vertical orientation; laying it flat shifts the trip curve. Footprint is 120 mm deep by 90 mm wide by 265 mm tall — the S0 frame keeps the gland-plate fill factor manageable in a 600 mm wide enclosure. Rated 690 V insulation voltage, AC-3 switching duty up to 690 V — covers 400 V, 480 V, 575 V, and 600 V line supplies without derating the voltage class.
Power ratings across common line voltages
At 400 V the starter is rated 550 W; at 460/480 V it delivers 0.75 hp; at 575/600 V also 0.75 hp — the motor full-load current at 480 V is 1.6 A, at 600 V it is 1.3 A. At 690 V the rating climbs to 1 100 W — useful for 690 V mining or marine distribution where the step-down transformer is upstream of the MCC. The supplied contactor is 3RT2023-1AK60; the link module is 3RA2921-1AA00; the busbar adapter is 3RA2922-1AA00 — all three are included, so no separate ordering for the reversing interlock hardware.
Thermal environment and pollution class
Operating ambient range is -20 to +60 °C — the bimetallic overload compensates across this band, but above 40 °C the trip current setting should be derated per the IEC 60947-4-1 derating curve. Pollution degree 3 means the unit is rated for conductive contamination (condensation, light dust) typical of industrial control panels without a sealed enclosure — no conformal coating required for the internal clearances. Storage range -50 to +80 °C and transport range -55 to +80 °C — the starter can sit in an unheated warehouse or ship in a non-climate-controlled truck without damage.
Lifecycle and compliance — current production, RoHS dated
RoHS compliance date is 03/01/2017 — the substance prohibition per EU Directive 2011/65/EU is met; no REACH SVHC declaration is in this record, but the RoHS date covers the standard industrial exemption set. The supplied sub-assemblies (contactor, link module, busbar adapter) are all current-production SIRIUS catalog items — no orphaned parts inside the assembly.
