Integrator's spec recap — 3RT2047-1SF30
Its coil accepts 83–150 V AC/DC via screw-type terminals, with an inrush peak of 25 A and a holding draw of 2.4 VA at 50/60 Hz. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when panel layout forces an odd orientation. Rated switching frequencies vary by duty: AC-1 (resistive) at 900 operations/hour, AC-3 (motor start/run) at 850/h, AC-2 at 350/h, and AC-4 (plugging/inching) at 200/h. The AC-3e rating also sits at 850/h. Mechanical life is typical 5 million cycles, with an MTBF of 52 years — a solid figure for a machine-tool or conveyor line that runs multiple shifts.
DIN-rail integration & clearances
The main circuit accepts solid conductors 2.5–16 mm² and stranded 6–70 mm²; auxiliary circuits take 2x (0.5–1.5 mm²) solid or stranded, or 2x (0.75–2.5 mm²).
Switching performance & contact ratings
Arcing time runs 10–20 ms, with make/close times of 38–57 ms for both AC and DC coil supplies. The auxiliary switch is included. For DC switching, the contactor is rated 10 A at 24 V, 2 A at 48 V, and 2 A at 60 V. The main contacts are rated for 10–2 (likely a make/break or utilization category range per the manufacturer's coding).
