Auxiliary/control wiring uses solid or stranded 2x (0.25-2.5 mm²) conductors. Mechanical endurance is rated at 10,000,000 operating cycles typical, with switching frequencies varying by duty: 800 cycles/hour at AC-1, 750 at AC-3 and AC-3e, 300 at AC-2, and 130 at AC-4. ## Dimensions and Clearances for Panel Integration The contactor measures 172 mm high, 120 mm wide, and 170 mm deep. The auxiliary switch is included as standard. The auxiliary contacts are rated for 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V — covering typical control circuit voltages.","metaTitle":"Siemens SIRIUS 3RT1056-7AB36-0SF1 Power Contactor, Size S6,","metaDescription":"Siemens SIRIUS 3RT1056-7AB36-0SF1 power contactor, Size S6, 170 mm depth, 172 mm height, 120 mm width.
