Three-pole, Size S2 frame, screw terminals. The AC-3 rating means it's sized for switching three-phase squirrel-cage motors up to 18.5 kW under full-load starts — the usual duty for conveyor, pump, and fan drives in a control panel. This part carries a lifecycle stage of 'current' but is explicitly marked as a phased-out product in the description. The official successor is the SIRIUS 3RT2 series. For BOM continuity, the 3RT2 is the drop-in replacement path for new designs. ## Deployment Context The 75 °C ambient rating means it can sit in a crowded panel without forced cooling — useful for retrofit into existing switchgear where airflow is limited. The 15-unit multi-unit packaging suggests it was originally specified for panel builders running a batch, not single-unit spares.","metaTitle":"Siemens 3RT1035-1AM70-0KR0-ZW96 Power Contactor, AC-3 40A, 1","metaDescription":"Siemens SIRIUS 3RT1035-1AM70-0KR0-ZW96 power contactor, AC-3 40 A, 18.5 kW / 400 V.
