It carries a 575-600 V AC/DC coil, so it suits installations where the control voltage is at the higher end of the standard range — common in 600 V class North American panels or 575 V Canadian plant lines. The contactor includes an auxiliary switch rated 10 A at 24 V, 2 A at 48-60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 6 A at 230 V — covering the typical control-circuit voltages a panel builder would encounter. The auxiliary contacts are screw-type terminals, matching the main coil termination style.
Dimensions and mounting — fits the S12 footprint
The 3RT1476-6AT36 measures 160 mm wide, 225 mm deep, and 214 mm high — the standard S12 contactor envelope. It mounts via screw fixing with a single 11 mm hole, and the mounting position allows a vertical surface with +/-90° rotation or +/-22.5° tilt front-to-back. Power-side cable termination accepts stranded conductors from 70 to 240 mm² — sized for the main circuit. The auxiliary and coil terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²).
Operating conditions and switching performance
The contactor's mechanical life is typically 10 million operations. Arcing time is 10-15 ms, and switching times at both AC and DC are 60-100 ms. The power factor at 50 Hz is 0.9, and at 60 Hz ranges from 0.8 to 1.1.
