It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, so it integrates into standard industrial enclosures without special adapters. Coil termination uses spring-type terminals — no screw torque to verify, just strip and push. The main circuit accepts solid conductors from 2.5 to 16 mm² and stranded from 6 to 70 mm², covering motor feeds up to the S3 current band. ## Mounting and Clearance Constraints The contactor body measures 70 mm wide by 140 mm high by 152 mm deep. Side clearance to adjacent devices is 10 mm; forward clearance is 20 mm; upward and downward clearance is 10 mm each. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, which helps when routing cables in a crowded gland plate.","metaTitle":"Siemens 3RT2047-3NB30-0CC0 SIRIUS Power Contactor, S3 Size","metaDescription":"Siemens 3RT2047-3NB30-0CC0 SIRIUS power contactor, S3 size, spring-type coil terminals, screw and snap-on DIN rail mount.
