Coil operates on 50 Hz (0.8...1.1 x rated voltage) or 60 Hz (0.85...1.1 x rated voltage), so it's fine on either supply frequency as long as the control transformer matches. Side-by-side mounting is allowed with a 6 mm gap at the side — no forced spacing, so you can pack contactors tight in a multi-motor panel. The front face carries IP20, the terminals are IP00 (finger-safe only once wired). Ambient range during operation is -25 to +60 °C, which covers most unheated plant floors. Terminals accept screw-type connections: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²) for solid/stranded. That's enough for the control wiring and the main circuit tails up to 4 mm² — typical for a contactor this size.","metaTitle":"Siemens 3RT1026-1AL20-ZW97 SIRIUS Power Contactor","metaDescription":"Siemens 3RT1026-1AL20-ZW97 SIRIUS S0 power contactor. 11 kW at 400 V AC-2, 15.5 A AC-4. 50/60 Hz coil.

It uses the same S0 frame, 45 mm width, and DIN-rail mounting, so it drops into the same panel slot. The coil voltage and frequency range are identical, meaning no control-circuit changes. The 3RT2026 offers higher breaking capacity in the same footprint."},{"question":"What is the difference between 3RT1026 and the successor 3RT2026?","answer":"Both are S0 frame contactors with the same 45 mm width and DIN-rail mounting. The 3RT2026 uses an improved arc chamber and contact materials, giving it higher breaking capacity in the same physical footprint. The coil voltage and frequency range are identical, so the 3RT2026 is a drop-in replacement without control-circuit changes."},{"question":"Where can I buy 3RT1026-1AL20-ZW97 available via RFQ confirmation?","answer":"This part is sourced to order; availability and pricing are confirmed at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1026-1AL20-ZW97","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/3RT1026-1AL20-ZW97 when reusing this data.
