The coil accepts 48 to 80 VDC, with pickup at 0.8x rated value and dropout below that; inrush current peaks at 1 A. The S2 frame size and 55 mm width are the first fit check: this contactor occupies a standard 55 mm wide DIN-rail footprint. The arcing time of 10–20 ms and switching rates (700 ops/h at AC-1, 500 ops/h at AC-3, 150 ops/h at AC-4) tell you the thermal duty cycle — AC-4 (plugging/inching) derates the contactor significantly, so plan the application accordingly.","metaTitle":"Siemens 3RT2038-1NE30 SIRIUS Power Contactor, S2, 48-80 VDC","metaDescription":"Siemens 3RT2038-1NE30 SIRIUS power contactor, size S2, 48-80 VDC coil, screw terminals.
