Product details

SIRIUS S2 Power Contactor – 3RT1535-1AU00

Rated operational current at AC-1 maximum is 1,000 cycles per hour, and the main circuit impulse withstand is 6 kV. The auxiliary circuit shares the same 6 kV impulse rating. Coil draws 12.5 VA at 50 Hz, with a power factor of 0.36 at 60 Hz. Switching times: AC operate 10–30 ms, arcing time 10–15 ms. The magnet coil uses screw-type terminals; main and auxiliary/control circuits also terminate via screw terminals.

Termination and Wiring

Main circuit screw terminals accept solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max. 2x (0.75–4 mm²). Stranded: 2x (0.75–25 mm²). AWG for main contacts: 2x (18–2). Auxiliary and control circuit terminals share the same screw-type design. Side clearance of 6 mm is required when mounting adjacent to other devices.

Frequently asked questions

What is the depth of 3RT1535-1AU00?
