The screw-type main terminals accept up to 2x 10 mm² or 1x 8 AWG. At 45 mm wide and 85 mm tall, the S0 footprint fits standard distribution board pitch. Side-by-side mounting is permitted — no derating gap required — which saves rail space on a multi-contactor motor starter group. Depth is 140 mm, so check gland plate clearance if the panel is shallow. The front face carries IP20 protection; the terminals themselves are IP00, meaning the wiring zone needs enclosure-level protection against accidental contact. For Type 1 coordination (contactor may need replacement after fault), the fuse can go up to 63 A. That gives the panel builder a clear selectivity boundary: stay at 25 A if you want the contactor to survive a downstream weld or short.","metaTitle":"Siemens 3RT1024-1AP64 SIRIUS Power Contactor, S0, 12.5 A AC-","metaDescription":"Siemens 3RT1024-1AP64 SIRIUS power contactor, size S0, 12.5 A AC-4 at 400 V.

AC-4 covers reversing, inching, and plugging duty — the most severe switching condition for a contactor because it makes and breaks the full locked-rotor current. If your application cycles a motor direction or jogs the load, this is the rating that governs contactor life, not the AC-3 motor-start figure."},{"question":"Will the 3RT1024-1AP64 drop into a panel specified for the 3RT1023-1AL20?","answer":"Both are S0 frame contactors with the same 45 mm width and DIN-rail mounting, so the footprint and rail position are identical. The main difference is the coil voltage — the 3RT1024-1AP64 uses a different coil than the 3RT1023-1AL20. If the control voltage matches your existing circuit, the mechanical swap is straightforward; if not, you need to verify the coil rating before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1024-1AP64","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/3RT1024-1AP64 when reusing this data.
