Depth is 174 mm, which fits standard 200 mm deep enclosures with the door closed. ## Motor switching capability and duty cycles Rated 65 A at 480 V in AC-3 duty (motor switching), this SIRIUS contactor handles motors up to 15 hp at 230 V. Switching cycle rates: 500 operations per hour maximum in AC-3 and AC-3e duty, 700/h in AC-1 (resistive), 350/h in AC-2, and 150/h in AC-4 (plugging/inching). The AC-4 rate is the limiting factor for applications requiring frequent reversing or jogging. Arcing time spans 10 to 20 ms, and the closing/opening time at AC is 10 to 18 ms — fast enough for most motor starter coordination requirements. ## Environmental range and coil data This covers most indoor industrial panel environments without derating at the upper end. Coil consumption at 50 Hz is 0.36 A and at 60 Hz is 0.39 A — the coil draws slightly more at 60 Hz due to the lower inductive reactance. The magnet coil uses screw-type terminals. Auxiliary switch blocks are not included (no auxiliary switch fitted as standard). The main contact arrangement is 18 normally open and 1 normally closed (18 NO / 1 NC). This is a qualified Siemens SIRIUS contactor suitable for BOM-frozen designs.","metaTitle":"Siemens 3RT2038-1AN24 SIRIUS Power Contactor, 65 A AC-3","metaDescription":"Siemens 3RT2038-1AN24 SIRIUS power contactor, Size S2, 65 A at 480 V AC-3, screw-type terminals, DIN rail mount.
