The coil is rated 110 VDC, and the contactor carries DC switching ratings across a range of voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V, and 0.8 A at 440 V. That means for a 24 VDC load you can switch up to 10 A; at 110 VDC the limit drops to 1 A. The mounting position allows vertical surface mounting with +/-180° rotation and +/-30° tilt front-to-back.","metaTitle":"Siemens 3RT1516-2BF40 SIRIUS Power Contactor, Size S00, 110","metaDescription":"Siemens 3RT1516-2BF40 SIRIUS power contactor, size S00, 110 VDC coil, spring-loaded terminals, DIN-rail mount.
