Reversing starter, size S0 — what it packs
The 3RA2225-1HB24-0AP6 is a Siemens SIRIUS non-fused reversing motor starter in size S0. It ships as a pre-assembled unit with a 3RT2024-1AP60 contactor and a 3RA2921-1AA00 link module — no separate wiring for the reversing interlock. Rated for AC-3 duty up to 690 V, it delivers 3 000 W at 400 V and 4 000 W at 500 V. At 460/480 V it's rated 5 hp; at 575/600 V also 5 hp. The coil accepts 176…242 V at 50 Hz and 192…264 V at 60 Hz.
Panel fit and clearance envelope
Dimensions are 90 mm wide × 265 mm tall × 120 mm deep. Mounts via snap-on fastening to a 35 mm standard DIN rail in a vertical position. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards. This is a tight envelope — the backwards zero means the back of the unit can sit flush against the panel backplane. Rated for Pollution Degree 3, so it's suited for industrial environments with conductive contamination — typical for control panels near machine tools or conveyor lines.
Lifecycle and sourcing — current production
Sourced through independent distribution against an RFQ. Operating temperature range is -20…+60 °C; storage range -50…+80 °C; transport range -55…+80 °C. The -55 °C transport floor matters for cold-chain or airfreight in winter.
Wire termination and compliance
Main contacts accept stranded wire 1…10 mm², or 2×(2.5…6 mm²). The dual-wire entry is useful for daisy-chaining power through the starter without a separate terminal block. Substance prohibitance date is 03/01/2017 — the part complies with RoHS and REACH requirements as of that date.
