The screw-type main terminals accept 2x (10 … 50 mm²) stranded or 2x (0.25 … 2.5 mm²) solid, which covers the range from a 10 mm² motor feed up to a 50 mm² bus tie. ## What the AC-4 and AC-2 ratings mean for your load profile AC-4 is the hardest thermal and mechanical duty class; the 80 A figure means this contactor handles a 400 V motor that draws 80 A in the locked-rotor condition without welding the main poles. For comparison, the AC-3 switching capacity (not listed directly here) would be higher — AC-3 breaks running current, not locked-rotor — so if your application is pure across-the-line starting and running, you have headroom above 80 A. The AC-2 rating of 45 kW at 400 V applies to slip-ring motor duty where the contactor switches the rotor circuit — wound-rotor motors in cranes, hoists, or conveyors with secondary resistance starting. If your BOM calls for a contactor on a slip-ring motor secondary, this is the rating to size against. At 690 V the rated motor power drops to 25.4 kW — a derate that reflects the higher arc energy at elevated voltage. If your line runs 690 V, confirm that 25.4 kW covers your load; if not, step up to the S6 frame. ## Operating conditions and enclosure integration Rated for -25 to +60 °C ambient during operation, with storage tolerance from -55 to +80 °C. The terminal area itself is IP00, so live bus bars are exposed if the contactor is mounted without a shrouded terminal cover. Side-by-side mounting is permitted (no derate gaps needed), which is typical for SIRIUS S3 contactors in a motor control centre lineup. If the panel environment sees heavy dust or conductive fibres, consider a conformal-coated variant.","metaTitle":"Siemens 3RT1046-3AP06 SIRIUS S3 Power Contactor, 80 A AC-4","metaDescription":"Siemens 3RT1046-3AP06 SIRIUS S3 power contactor, 80 A AC-4 at 400 V, 45 kW AC-2.

The difference is in the coil voltage and the switching ratings — the 3RT1046-3AP06 carries higher AC-4 and AC-2 currents. If the original 3RT1044-1FB46 coil voltage matches the 3RT1046-3AP06 control circuit, the swap is a straight drop-in; verify the coil tag before ordering."},{"question":"What is the mechanical life of this contactor?","answer":"The typical mechanical life is 10 000 000 operations — that is the rated figure for the S3 frame under standard operating conditions."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1046-3AP06","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/3RT1046-3AP06 when reusing this data.
