The 10 mm forward clearance is the binding constraint when panel depth is tight. ## Duty-cycle limits and mechanical life Mechanical life expectancy is 30 million operating cycles typical — the failure mode is contact wear, not the solenoid. The switching frequency ceiling varies by duty: 1,000 ops/h in AC-1 (resistive), 750 ops/h in AC-2 and AC-3 (motor starting), and 250 ops/h in AC-4 (plugging/inching). Exceeding these rates accelerates contact erosion and raises the probability of a welded contact before the rated mechanical life. The 60 °C ceiling at full rated load means derating is needed above 40 °C ambient in a sealed enclosure — plan the thermal budget accordingly. ## Auxiliary contact ratings and conductor sizing At 400 V the rating is 3 A — this is the value that governs most 400 V control circuits. The motor horsepower rating at 230 V is 2 hp, which maps to a typical 1.5 kW motor at that voltage. Conductor cross-section accepted: solid or stranded 0.5 to 4 mm², and 2x (0.5 to 4 mm²) for looping through. The spring-type terminals on the coil side accept the same range, which simplifies wire selection for the control transformer feed.","metaTitle":"Siemens 3RT2017-2BG41 SIRIUS S00 Power Contactor","metaDescription":"Siemens 3RT2017-2BG41 SIRIUS S00 power contactor, current production. 3 A at 400 V auxiliary contacts, spring-type terminals, 45 mm wide.
