The Siemens 3RT2625-1NB35 is a SIRIUS contactor with a screw-type terminal coil rated for AC/DC 21–28 V. It switches loads up to 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — the 400 V figure is the one that governs most three-phase motor circuits in European panels. The 45 mm width and 165 mm depth fit standard enclosure backplates; the mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward.
Solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or 2x 4 mm². Stranded: 2x (1–2.5 mm²) or 2x (2.5–10 mm²). At 40 °C ambient, a single 6 mm² conductor is accepted; at 60 °C, one 10 mm² or two 6 mm². No auxiliary contact block attaches directly (Attachable: 0).
