It's rated for 10 A at 24 V for the coil, and AC-4 duty at 15.5 A at 400 V, which is the heavy reversing/plugging load that kills smaller contactors fast. That's the duty cycle that wears contacts fastest. The coil pulls 10 A at 24 V, so size your control transformer and fuse accordingly. The S0 frame is 45 mm wide and 85 mm tall, with a 90 mm depth — fits standard DIN-rail enclosures. ## Coordination and wiring Main circuit wiring accepts screw terminals: 2x (0.25 to 2.5 mm²) solid or 2x (1 to 2.5 mm²) stranded, up to 2x 10 mm².","metaTitle":"Siemens 3RT1026-3AG20-ZX95 SIRIUS S0 Contactor, 10 A at 24 V","metaDescription":"Siemens SIRIUS power contactor 3RT1026-3AG20-ZX95, size S0, 10 A at 24 V, AC-4 15.5 A at 400 V, screw terminals, DIN rail mount.

Availability and current pricing are confirmed at quote time."},{"question":"What is the AC-4 rating and why does it matter?","answer":"The AC-4 rating is 15.5 A at 400 V. That's the maximum current the contactor can handle during frequent starts, stops, or reversing — the harshest duty for a contactor. If your motor load exceeds this, step up to a larger frame."},{"question":"Will 3RT1026-3AG20-ZX95 drop into a panel specified around 3RT1023-1AL20?","answer":"Both are SIRIUS S0 contactors on a 35 mm DIN rail, so the mechanical footprint is the same. The 3RT1026 has a higher AC-4 current rating (15.5 A vs the 3RT1023's lower rating), so it's a direct replacement if the wiring and fuse coordination are adjusted accordingly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1026-3AG20-ZX95","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/3RT1026-3AG20-ZX95 when reusing this data.
