Product details

Siemens 3RT1065-2AR36 SIRIUS S10 Power Contactor

It uses spring-type terminals for the coil connection and screw fixing for panel mounting. The contactor measures 202 mm deep, 145 mm wide, and 210 mm high, fitting into the S10 frame size. Switching frequency varies by duty class: 800 cycles/hour at AC-1, 500 at AC-3/AC-3e, 250 at AC-2, and 130 at AC-4.

Wiring and Clearance

Main power terminals accept stranded cable from 70 to 240 mm². Minimum clearance distances: 10 mm upwards, downwards, and to the side; 20 mm forwards. A single 11 mm diameter mounting hole is provided for screw fixing.

Auxiliary and Coil Details

An auxiliary switch is integrated. Its contact ratings: 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, and 1 A at 110 V. Arcing time is 10-15 ms. The coil pick-up voltage is 0.8 x rated value; drop-out is 1.1 x rated value.
