What this contactor delivers
The Siemens SIRIUS 3RT2038-1AP60 is an S2-frame power contactor rated for motor switching and resistive loads. Its 55 mm width fits standard DIN-rail spacing; the 130 mm depth clears typical enclosure depths without crowding gland plates or busbars. Switching frequency depends on duty class: AC-1 (resistive) allows up to 700 ops/h, AC-3 motor duty allows 500 ops/h, and AC-4 (plugging/reversing) limits to 150 ops/h. The magnet coil connects via screw terminals, supporting solid or stranded wire from 0.5 to 2.5 mm².
Mounting and integration
Screw-and-snap mounting on 35 mm DIN rail per DIN EN 60715. The contactor can be mounted vertically with +/-180° rotation, and tilted forward/backward by +/-22.5° on a vertical surface – useful for tight panel layouts or cable-entry constraints. Auxiliary switch block is built in; main contact configuration is 18...1. Clearances: 10 mm upwards, 10 mm forwards, 6 mm to the side, 10 mm downwards.
