At 40 °C ambient, the minimum permissible cross-section is 16 mm² — relevant for sizing the power wiring under full load. The 55 mm width and 112 mm height fit standard S2 contactor spacing on the rail. Depth is 164 mm, which includes the arc chamber and terminal clearance — factor that into gland-plate depth and enclosure fill calculations. Side-by-side mounting is permitted, so no mandatory spacing gap between units. In a panel environment that's standard — the enclosure provides the overall IP rating. RoHS compliance date is marked as 05/01/2012, confirming the contactor meets the substance restrictions of the RoHS directive from that date forward.","metaTitle":"Siemens 3RT1035-1AF04 SIRIUS Power Contactor, S2, 55 mm, AC-","metaDescription":"Siemens 3RT1035-1AF04 SIRIUS power contactor, size S2, 55 mm width, 22 kW at 500 V AC-3.
