At 400 V and 60 °C ambient, it handles 121 kW of motor load; at 230 V and 60 °C, 70 kW. At 690 V the rating is 65 kW. Maximum switching frequency varies by duty: 800 operations per hour under AC-1, 750 under AC-3, and 130 under AC-4. Fastening is by screw fixing. Side-by-side mounting is permitted, which simplifies dense panel layouts. Dimensions: 172 mm high, 120 mm wide, 170 mm deep. Pollution degree 3 rated, meaning it tolerates conductive pollution typical in industrial enclosures. Minimum conductor cross-section for the main circuit is 95 mm² at both 40 °C and 60 °C ambient. ## Coil data and operating conditions Power factor at rated voltage is 0.9 at both frequencies. Coil inrush and hold currents: 6 A at 24 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, and 3 A at 400 V. The surge suppressor design uses a varistor, which clips voltage spikes from the coil circuit. Substance prohibition compliance date is 03/01/2017, indicating RoHS and REACH conformance from that date forward.","metaTitle":"Siemens 3RT5056-6AV36 SIRIUS Power Contactor, 121 kW at 400","metaDescription":"Siemens 3RT5056-6AV36 SIRIUS power contactor, size S6.
