These are the minimum air gaps for arc flash and heat dissipation — don't crowd the contactor against cable ducts or adjacent devices. ## Coil and switching ratings The magnet coil uses spring-type terminals (cage clamp) — no screw torque to verify, which speeds panel wiring. Coil ratings at 24 V rated value: 6 A. At 48 V: 2 A. At 60 V: 2 A. At 110 V: 1 A. At 125 V: 0.9 A. At 220 V: 0.3 A. At 400 V: 3 A. At 440 V: 0.6 A. These are the contact ratings at those voltages — match your load voltage to the appropriate row for the actual switching capacity. Motor load rating at 230 V: 3 hp. At 400 V: 3 A. The AC-1 (resistive) maximum operating frequency is 1,000 operations per hour; AC-4 (plugging/reversing/inching) at 250 ops/h. For high-duty-cycle applications like frequent reversing, the AC-4 limit governs — don't exceed 250 cycles per hour. For fine-stranded or ferrule-terminated wire, the dual-entry specification allows 2x (0.5 to 2.5 mm²). The spring-type terminals on the coil side match the same cage-clamp family — consistent tooling across the contactor. ## Environmental limits Storage temperature: -55 to +80 °C.","metaTitle":"Siemens 3RT2026-2AL24 SIRIUS Power Contactor, S0, 24 VDC Coi","metaDescription":"Siemens 3RT2026-2AL24 SIRIUS power contactor, size S0, 24 VDC coil, spring-type terminals, 45 mm width, 144 mm depth.
