The coil is rated 20–33 V, with an inrush peak of 6.5 A and a holding draw of 3.5 VA at both 50 and 60 Hz. That coil voltage range covers standard 24 VDC control supplies with margin — expect pickup at 0.8× rated value (about 16 V) and dropout below that, typical for DC-operated contactors. Main contact wiring accepts solid conductors 2.5–16 mm² or stranded up to 70 mm², so it handles motor feeders up to about 25–30 kW without needing a separate terminal adapter. ## Integration and mounting notes The screw-type coil terminals accept 2×(0.5–1.5 mm²) or 2×(0.75–2.5 mm²) solid or stranded — standard control wiring sizes.","metaTitle":"Siemens 3RT2046-1NB30-0UA0 SIRIUS Power Contactor, S3, 152 m","metaDescription":"Siemens SIRIUS power contactor 3RT2046-1NB30-0UA0, size S3, screw terminals, 152 mm depth, 70 mm width.
