The contactor measures 172 mm high by 120 mm wide by 170 mm deep, mounts via screw fixing, and the mounting position allows vertical surface mounting with ±90° rotation or ±22.5° tilt forward/back — useful when shoehorning it into a crowded panel section. It carries an auxiliary switch and arcing time is 10-15 ms; operate times at both AC and DC are 40-60 ms. ## Switching rates and duty cycles Maximum switching rates vary by duty class: AC-1 (resistive) at 800 ops/h, AC-2 at 400 ops/h, AC-3 and AC-3e at 1,000 ops/h, and AC-4 (plugging/inching) at 130 ops/h. For a motor-switching application like a conveyor or pump, the AC-3/AC-3e rating is the one that governs — 1,000 operations per hour means it can cycle every 3.6 seconds continuously without exceeding thermal limits. Power circuit accepts stranded cable 25-120 mm². The coil and auxiliary connections handle solid or stranded conductors: 2x (0.5-1.5 mm²), 2x (0.75-2.5 mm²), or max 2x (0.75-4 mm²). Four mounting holes, 9 mm diameter, one per corner.","metaTitle":"Siemens 3RT1054-6AT36 SIRIUS Power Contactor, Size S6, 25-12","metaDescription":"Siemens 3RT1054-6AT36 SIRIUS power contactor, size S6.
