The contactor's DC switching capacity is specified per voltage: at 24 V it handles 10 A, at 48 V and 60 V it handles 2 A, at 110 V it handles 1 A, at 125 V it handles 0.9 A, at 220 V it handles 0.3 A, at 400 V it handles 3 A, at 480 V it handles 14 A, at 500 V it handles 2 A, and at 600 V it handles 11 A. These values define the maximum continuous current the main contacts can interrupt at each DC voltage level — critical for sizing the contactor to the load's voltage and current draw. The contactor occupies a 45 mm width, 70 mm height, and 73 mm depth footprint. The mounting position is hanging on a horizontal surface. The coil connection uses spring-type terminals accepting solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm².","metaTitle":"Siemens SIRIUS 3RT2018-2XF41-2LA2 Contactor, 72-125 VDC Coil","metaDescription":"Siemens SIRIUS 3RT2018-2XF41-2LA2 contactor, size S00, 72-125 VDC coil, spring-type terminals.
