SIRIUS Size S10 contactor for motor and resistive loads
The Siemens 3RT1363-6AP36 is a SIRIUS Size S10 contactor with a screw-type coil terminal block accepting AC supply at 100-250 V, 50/60 Hz. It is designed for switching motor loads and resistive circuits in industrial control panels, with a rated coil power draw of 7 VA at both 50 Hz and 60 Hz. The contactor includes two built-in auxiliary contacts (instantaneous) rated for switching at various voltages — 3 A at 400 V AC, 4 A at 230 V AC, and 2 A at 690 V AC — giving it flexibility for feedback or interlocking in the same enclosure. Mounting is via screw fixing to a vertical surface, with the body able to be rotated ±180° and tilted forward or backward up to ±30° at 0° rotation. Clearances of 10 mm upward, 10 mm downward, 10 mm at the side, and 20 mm forward are required for heat dissipation and arc quenching. The Size S10 frame measures 196 mm high, 140 mm wide, and 153 mm deep — a substantial footprint that needs a solid backplate or sub-panel.
Thermal range and auxiliary contact capacity
Rated for operation from -40 °C to +60 °C and storage from -40 °C to +70 °C, this contactor suits unconditioned enclosures or outdoor-adjacent installs within that band. The auxiliary contacts carry full ratings across the voltage sweep: 3 A at 24 V, 1.5 A at 48 V, 0.55 A at 110/125 V, 0.3 A at 220 V, 4 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 2 A at 690 V — all AC values. These cover most control-circuit voltages found in European and North American panels.
