It mounts via screw fixing or snap-on onto 35 mm DIN rail per DIN EN 60715, with a width of 55 mm, height of 114 mm, and depth of 174 mm. Main contact wiring accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors at the screw-type terminals. The coil is also screw-terminal terminated. No auxiliary switch is integrated on this base variant. ## Switching capacity and operating rates across duty classes The contactor's maximum operating rate varies by duty class: 700 cycles per hour at AC-1 (resistive), 500 cycles per hour at AC-3 (standard motor starting), and 150 cycles per hour at AC-4 (plugging/inching). The AC-3e rating matches the AC-3 rate at 500 cycles per hour. Arcing time spans 10 to 20 ms, with closing time between 10 and 18 ms. These figures define the thermal and mechanical limits for repetitive switching applications. Clearance requirements are 10 mm upward, forward, and downward, with 6 mm at the sides. The S2 frame contactor occupies 55 mm of DIN rail width. Screw fixing provides a secure mount in high-vibration environments; snap-on mounting suits rapid assembly. The ±180° rotation and ±22.5° tilt allowances simplify orientation in multi-row panels. Clearance of 10 mm on three sides and 6 mm laterally ensures adequate air circulation for heat dissipation within the -25 to +60 °C operating range.","metaTitle":"Siemens 3RT2038-1AG24 SIRIUS Power Contactor, 65 A at 480 V","metaDescription":"Siemens 3RT2038-1AG24 SIRIUS power contactor, S2 frame, 65 A at 480 V.
