The Siemens 3RH2140-2AK60 is a SIRIUS auxiliary contactor in the S00 frame size, carrying 4 instantaneous normally-open contacts. It mounts via screw or snap-on onto a standard 35 mm DIN rail, with a 45 mm width and 73 mm depth that fits the S00 footprint — three units side by side occupy 135 mm of rail space. The coil is rated for 24 V at 50/60 Hz, with a pickup range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz.
The 4 NO contacts handle 10 A at 24 V and 230 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, and 0.26 A at 600 V. At DC voltages, the 60 V rating is 4.7 A, dropping to 0.5 A at 440 V and 0.26 A at 600 V. AC switching time is 4 to 15 ms.
