Its compact footprint — 45 mm wide, 57.5 mm tall, 72 mm deep — fits standard 35 mm DIN rail (DIN EN 50022) via screw or snap-on mounting, making it a direct panel integration for new builds or retrofits. The AC-3 rated operational voltage goes up to 690 V, so this contactor can switch three-phase induction motors at 400 V or 480 V line-to-line without derating the main poles. The 48 V AC coil draws 0.27 W holding power at both 50 Hz and 60 Hz, which is a low continuous burden on the control transformer — useful when multiple contactors share a single supply. This is a common pain point with older contactors that need a higher minimum load to break through oxide films. The auxiliary contact ratings at 230 V (6 A), 400 V (3 A), and 690 V (1 A) define the resistive switching capacity for control circuits. For inductive loads like small relays, derate per the AC-15 or DC-13 curves — the listed values are for AC-1 resistive duty. It is intended for dry indoor enclosures — not washdown or outdoor use. The shock resistance of 9.8g for 5 ms (sine pulse) covers most vibration profiles in standard industrial machinery. Screw-type terminals on both main and auxiliary circuits accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) finely stranded with ferrule. This covers standard control wiring up to 14 AWG. For short-circuit protection, type of coordination 1 requires a 35 A gL/gG fuse (e.g., NH 3NA), while type 2 coordination requires a 20 A fuse. The 6 kV rated surge voltage withstand means it can handle typical transient overvoltages in 400 V systems without additional suppression. The screw terminals and S00 footprint are common across the 3RT7014 series, so swapping between coil voltages (e.g., 24 V AC, 110 V AC) requires only the coil change, not a panel re-layout.","metaTitle":"Siemens 3RT7014-1AH02 Contactor, S00, 48V AC Coil, 3-Pole","metaDescription":"Siemens 3RT7014-1AH02 contactor, size S00, 3-pole, 48V AC 50/60Hz coil.
