The 10-15 ms arcing time and 40-60 ms operate times (both AC and DC) are typical for this frame class — the arcing figure matters for coordination with upstream short-circuit protection, especially in a panel with tight selectivity margins. ## Power wiring and auxiliary connections Main power terminals accept stranded cable from 25 mm² up to 120 mm², sized for the full S6 current rating. The auxiliary switch block (screw-type terminals) handles solid or stranded conductors: 2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or max 2x 0.75-4 mm². Mounting is screw-fix with a vertical surface — the contactor can be rotated ±90° or tilted ±22.5° front/back, giving panel builders flexibility on busbar orientation.","metaTitle":"Siemens 3RT1056-6AM36 SIRIUS Power Contactor, S6, 200-220V C","metaDescription":"Siemens 3RT1056-6AM36 SIRIUS power contactor, size S6, 200-220 V AC coil, screw terminals.

The 3RT1056-6AM36 carries a 200-220 V AC coil; if your panel voltage matches, the 1AB36 may drop in without rewiring, but always confirm the auxiliary contact configuration on your specific build."},{"question":"Will 3RT1056-6AM36 drop into a panel that was specified around 3RT1056-1AB36 without rewiring?","answer":"Yes, the S6 frame size and mounting footprint are identical across the 3RT1056 family, so the 3RT1056-6AM36 will physically replace a 3RT1056-1AB36 in the same panel. The main power wiring (25-120 mm² stranded) and auxiliary terminal capacities are the same. The only difference to check is the coil voltage: the 6AM36 uses 200-220 V AC, while the 1AB36 may differ — confirm your control voltage before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1056-6AM36","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/3RT1056-6AM36 when reusing this data.
