Mounting is by screw fixing through a single 9 mm diameter hole. The enclosure dimensions are 172 mm high by 120 mm wide by 170 mm deep. ## Switching performance and ratings The contactor is rated for AC switching duty with operating times of 40 to 60 ms on both AC and DC control. Arcing time is specified at 10 to 15 ms. Maximum switching frequencies vary by duty class: 800 operations per hour for AC-1 (resistive), 300 for AC-2, 750 for AC-3 (standard motor starting), 130 for AC-4 (inching/plugging), and 750 for AC-3e. The mechanical service life is a typical 10,000,000 operations. The auxiliary switch is present and rated for 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V.","metaTitle":"Siemens SIRIUS 3RT1056-6AP36-0UA0 Power Contactor, Size S6,","metaDescription":"Siemens SIRIUS 3RT1056-6AP36-0UA0 power contactor, Size S6. 220-240VAC coil.
