The 3RT2336-1AN20 is a Siemens SIRIUS S2-frame contactor with an AC coil, screw-type coil terminals, and an integrated auxiliary switch. Rated at 10 A at both 24 V and 230 V AC, this contactor handles typical control and lighting loads within that current envelope. The 10 000 000 mechanical operations rating gives a baseline for duty-cycle planning — expect the auxiliary contacts or coil to be the wear-out path before the main contacts at light resistive loads.
Integration — DIN rail and wiring
The S2 frame occupies 75 mm width, 114 mm height, and 130 mm depth. These numbers govern the minimum enclosure size and the spacing to adjacent components for heat dissipation and arc flash clearance. Main contact wiring accepts two conductors per terminal: 2x (0.5... 1.5 mm²) solid or stranded, or 2x (0.75... 2.5 mm²). The screw-type coil terminals match the same wire range. Strip length and torque follow standard Siemens S2 practice — verify against the terminal marking when terminating.
