Auxiliary contacts are built in, rated 10 A at 24 V, 2 A at 48 V, and 1 A at 110 V — enough for direct PLC input feedback without an interposing relay on most 24 VDC control circuits. ## Duty Ratings and Switching Frequency Switching frequency varies by duty class: 800 cycles/hour in AC-1 (resistive), 400 in AC-2 (slip-ring motors), 1,000 in AC-3 (squirrel-cage motors), and 130 in AC-4 (plugging/inching) (–,). The AC-3e rating also supports 1,000 cycles/hour. For a conveyor drive running AC-3 duty, that's roughly one start every 3.6 seconds — line speed is not the limiter here. Arcing time runs 10–15 ms; pick-up and drop-out are both 40–60 ms on AC or DC (–). Fastened by screw fixing through a single 9 mm hole. The mounting surface must be vertical, with ±90° rotatability and ±22.5° tilt front-to-back. The S6 frame measures 120 mm wide × 172 mm high × 170 mm deep — check your gland plate and DIN-rail backplane clearance before committing the panel layout. ## Wire Range and Terminals Power circuit accepts stranded wire 25–120 mm². Auxiliary/coil terminals take solid or stranded 2× (0.25–2.5 mm²). The spring-type coil terminals hold firmly without retorquing — useful in high-vibration environments like compressor skids. ## Environmental Range The wider storage window matters if this sits in an unheated warehouse before commissioning. The 3RT1054-2AB36 is listed at a current lifecycle stage — meaning it remains in the active portfolio with no announced end-of-life.","metaTitle":"Siemens 3RT1054-2AB36 SIRIUS Power Contactor, Size S6, 24 VD","metaDescription":"Siemens SIRIUS 3RT1054-2AB36 power contactor, size S6, 24 VDC coil.
