What This SIRIUS S3 Contactor Brings to the Panel
The 3RT2047-3NB30-0CC0 is a SIRIUS power contactor in the S3 frame size — the mid-range footprint that balances current capacity with panel density. 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.
