Physical footprint: 55 mm wide, 114 mm high, 130 mm deep. ## Coil and auxiliary specs The DC coil draws an inrush peak of 1.5 A; the holding current is not separately listed but the operating range covers -40 to +70 °C ambient. Storage temperature spans -55 to +80 °C. An auxiliary switch is included. The main contact rating is given as 18... 1 (likely a range for different duty categories, e.g., AC-3 / AC-4).","metaTitle":"Siemens 3RT2036-1XF40-0LA2 SIRIUS Contactor, 55 mm","metaDescription":"Siemens 3RT2036-1XF40-0LA2 SIRIUS contactor, size S2, 55 mm wide, 130 mm deep.
