The contactor carries two normally-open and two normally-closed instantaneous auxiliary contacts, rated for switching up to 4 A at 230 V, 3 A at 400 V, and 2 A at 690 V — covering most pilot-duty and small-load applications in a 400/690 V panel. Mounts via screw fixing on a vertical surface; the enclosure can be rotated ±180° or tilted forward/backward ±30° at 0° rotation, giving flexibility in tight cabinets. Dimensions are 225 mm high, 184 mm wide, 180 mm deep — a substantial footprint that fits standard S12 panel cutouts. ## Wiring and auxiliary contacts The auxiliary switch block is present and can accept up to two additional attachable contact blocks for expanding signal feedback. Pickup voltage threshold is 0.8 x rated (about 19.2 VAC minimum), dropout at 1.1 x rated (about 26.4 VAC maximum) — ensures reliable pull-in and avoids chatter on a sagging control bus.","metaTitle":"Siemens 3RT1375-6AE36 SIRIUS Contactor, Size S12, 24-60 VAC","metaDescription":"Siemens 3RT1375-6AE36 SIRIUS contactor, size S12, screw-type coil terminals, 24-60 VAC 50/60 Hz. 2 NO + 2 NC instantaneous contacts.
