Switching rates are duty-dependent: 800 operations/hour in AC-1 resistive loads, 750/h in AC-3 motor starting, and 130/h in AC-4 plugging/reversing. The 10–15 ms arcing time and 40–60 ms operate time (both AC and DC) are typical for this class — expect consistent pick-up and drop-out timing across the control range. Mounts via screw fixing on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back — gives flexibility in tight enclosures. Dimensions are 172 mm high, 120 mm wide, 170 mm deep. The single 9 mm mounting hole is standard for this frame size.","metaTitle":"Siemens 3RT1055-6AP30 SIRIUS Power Contactor, 160 A, S6 Size","metaDescription":"Siemens 3RT1055-6AP30 SIRIUS power contactor, S6 size, rated 160 A at 24-220 V.
