The depth matters for enclosure depth planning: at 152 mm, it clears most 200 mm deep cabinets with room for wiring ducts. Mounting is screw-and-snap-on onto 35 mm DIN rail per EN 60715, with ±180° rotation on a vertical surface and ±22.5° tilt forward/backward — flexible for tight retrofit panels where the rail orientation isn't perfectly plumb. ## Spring-Terminal Coil, Auxiliary Contact Built In The magnet coil uses spring-type terminals (push-in or screwdriver-actuated) — no screw torque, no loose strands, faster wiring on the control side. The contactor includes an auxiliary switch as standard, saving a separate add-on block for status feedback to a PLC or indicator light. Coil operating range is 20…33 V, with a pickup threshold at 0.8× rated value and a dropout at 1.1× full-scale — the 0.8 factor means it pulls in reliably even if the control supply sags to 16 V. Inrush current peaks at 6.5 A, then settles to 3.5 VA at 50/60 Hz. ## Operating Temp and Duty Cycles Rated for -25 to +60 °C operating ambient — the 60 °C ceiling covers most non-conditioned industrial enclosures; storage range is -55 to +80 °C. Maximum switching rates: 900 cycles/h in AC-1 (resistive), 850 in AC-3 (motor start/run), 250 in AC-4 (plugging/inching). The AC-3e rating matches the AC-3 rate at 850 cycles/h. Arcing time is 10…20 ms, and the contactor is rated for 10 million mechanical operations typical — the electrical life depends on the load current and duty class, but the mechanical floor is high enough for frequent cycling applications like conveyor indexing. ## Sourcing — Active Production, Quoted to Order Wire range: solid 2.5…16 mm² for the main circuit, stranded up to 70 mm², and 2×(0.5…2.5 mm²) for the auxiliary/coil terminals. The spring terminals on the coil accept solid or ferruled stranded without a ferrule — drop the stripped wire in and push.","metaTitle":"Siemens 3RT2046-3NB30-0CC0 SIRIUS Power Contactor, Size S3","metaDescription":"Siemens 3RT2046-3NB30-0CC0 SIRIUS power contactor, Size S3, 70 mm wide, 152 mm deep.
