The 90 mm width and 68 mm height keep panel layout compact for the S00 frame class. The assembly also carries horsepower ratings for North American voltages: 1.5 hp at 200/208 V, 2 hp at 220/230 V, 3 hp at 460/480 V, and 5 hp at 575/600 V. The 750 operations per hour maximum at AC-3 means this is sized for moderate cycling, not high-speed reversing applications like servo positioning. Terminal capacity accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² — sized for motor power wiring up to the 4 kW / 5 hp range. Clearance distances: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards against the DIN rail. The screw-type coil terminals match the main circuit terminal style, so one tool handles the whole assembly.","metaTitle":"Siemens 3RA2315-8XB30-1AK6 SIRIUS Reversing Contactor Assemb","metaDescription":"Siemens SIRIUS 3RA2315-8XB30-1AK6 reversing contactor assembly, Size S00, 3 kW at 400 V AC-3.

The 3RA2315-8XB30-1AK6 includes two 3RT2015-1AK62 contactors with a mechanical interlock — you'd need to add an interlock and wire the reversing circuit yourself with the 3RT6017-1AF01.

Electrically no — the 3RA2315-8XB30-1AK6 is a reversing assembly with two contactors and a mechanical interlock; the 3RT6017-1AF01 is a single contactor. You'd need to rewire the reversing circuit and add an interlock if using the single contactor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2315-8XB30-1AK6","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RA2315-8XB30-1AK6 when reusing this data.
