Product details

Siemens SIRIUS auxiliary contactor 3RH2140-1AN20, size S00, with 4 instantaneous contacts. Screw or snap-on to 35 mm DIN rail; 45 mm wide, 73 mm deep.

Mounting is flexible: on a vertical surface you can rotate it a full 180°, or tilt it ±22.5° forward/backward if you're squeezing it into an awkward spot. Clearances are modest—10 mm above and below, 6 mm at the sides—so it can live in tight subpanels.
