Product details

Siemens SIRIUS 3RT1064-2AT36 — S10 Power Contactor, Screw Fixing, Spring-Terminal Coil

It is rated for 10 A at 24 V DC, 2 A at 48 V DC, 2 A at 60 V DC, and 1 A at 110 V DC. The contactor measures 210 mm high, 145 mm wide, and 202 mm deep. This is a current-production part.

Wiring & Terminals

The magnet coil uses spring-type terminals — no screw torque to verify, just strip and insert. Main power terminals accept solid or stranded wire: 2x (0.25 to 2.5 mm²) for the auxiliary/control side, and stranded 70 to 240 mm² for the main power path. The single mounting hole is 11 mm diameter.

Switching Rates & Arcing

Maximum switching rates vary by duty: 750 cycles/hour at AC-1, 250 at AC-2, 500 at AC-3/AC-3e, and 130 at AC-4. Mechanical life is typical 10,000,000 operations.
