Three NO main contacts, three poles, IP20 on the front face. ## DIN-rail fit and panel clearance Width 45 mm, height 60 mm, depth 73 mm. The 6 mm clearance to adjacent devices at the side is the minimum air gap — no extra spacer needed for a standard panel layout. Pollution degree 3 rated, so it handles conductive dust environments typical of industrial control cabinets. The AC-12 operating current max is 10 A — that's the resistive load ceiling for the main circuit.","metaTitle":"Siemens 3RT1017-5BB42 SIRIUS Power Contactor, 24 VDC, 5.5 kW","metaDescription":"Siemens SIRIUS 3RT1017-5BB42 power contactor, size S00, 3-pole, 24 V DC coil, 5.5 kW at 400 V AC-2.
