SIRIUS S10 Power Contactor — 3RT1064-6AP36-3PA0
The Siemens 3RT1064-6AP36-3PA0 is a SIRIUS S10 power contactor with an integrated auxiliary switch, designed for motor switching and general load control in industrial panels. It uses screw-type terminals for the magnet coil and accepts stranded cable from 70 up to 240 mm² on the main circuit.
Fastened via screw fixing with a single 11 mm hole. Dimensions are 210 mm height, 145 mm width, and 202 mm depth — sized for standard S10 panel cutouts.
Duty Ratings and Switching Performance
Switching frequency varies by duty class: AC-1 (resistive) at 750 operations/hour maximum, AC-2 at 250 ops/h, AC-3 (motor starting) at 500 ops/h, AC-4 (plugging/inching) at 130 ops/h, and AC-3e at 500 ops/h. The coil rated voltage is 220–240 V, with an initial pickup threshold of 0.8× rated and a full-scale dropout at 1.1× rated.
The built-in auxiliary switch is rated for DC loads: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V.
Terminal capacity for control wiring: solid or stranded conductors accepted as 2× (0.5–1.5 mm²), 2× (0.75–2.5 mm²), or maximum 2× (0.75–4 mm²).
