Mounts via screw fixing on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back. Side-by-side mounting is permitted. The enclosure rating is IP00 overall, IP20 on the front with a cover or box terminal. Dimensions: 172 mm high, 120 mm wide, 170 mm deep. ## Electrical ratings and switching life The main current circuit uses screw-type terminals (cite:) accepting up to 95 mm² conductors at 40 °C or 60 °C (cite:,). Electrical life varies by duty: 800 cycles/hour at AC-1 (resistive), 750 at AC-3 (motor starting), and 130 at AC-4 (plugging/inching) (cite:,). The integrated varistor surge suppressor (cite:) clips coil-switching transients — no external snubber needed for most panels. Auxiliary contacts are included (cite:), with instantaneous switching rated at 6 A at 24 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V (cite:,).","metaTitle":"Siemens 3RT5056-6AR36 SIRIUS Power Contactor, 440-480 V Coil","metaDescription":"Siemens 3RT5056-6AR36 SIRIUS power contactor, size S6, 440-480 V AC coil, 65 kW at 690 V.

The difference is the coil voltage: 3RT5056-6AR36 uses a 440-480 V AC coil, while the 6AM36 variant uses a different coil voltage. If the panel's control voltage matches 440-480 V AC, it drops in without rewiring; otherwise, the coil circuit must be adapted."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT5056-6AR36","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/3RT5056-6AR36 when reusing this data.
