The Siemens 3RH1131-2AR60 is a SIRIUS auxiliary contactor in Size S00, carrying 3 normally-open and 1 normally-closed instantaneous contacts. It switches 10 A at 24 V rated value and 6 A at 230 V rated value, with a rated insulation voltage of 400 V at 50 Hz. The contact reliability is rated at one incorrect switching operation per 100 million operations at 17 V, 1 mA — suitable for low-energy signal circuits in control panels.
Mounts via screw and snap-on method to a DIN rail. The 73 mm depth, 45 mm width, and 60 mm height fit standard S00 contactor footprints. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward. Wire termination accepts 2x (0.25 to 2.5 mm²) solid conductors. Shock rated at 10g / 5 ms and 5g / 10 ms. IP20 protection on the front — suitable for enclosed panel environments, not washdown zones.
Compared to the 3RH2131-2AK60, this 3RH1131-2AR60 shares the same Size S00 frame, screw/snap-on mount, and 3 NO + 1 NC contact configuration. The key difference is the 3RH2131-2AK60 carries a different coil voltage variant. Both drop into the same panel footprint without rewiring — the 73 mm depth and 45 mm width are identical.
