The Siemens SIRIUS 3RH2131-2JC40 is a coupling relay designed for switching auxiliary circuits, sized S00 and carrying 3 NO instantaneous contacts.
This relay's contact ratings are specified per voltage: 10 A at 24 V and 230 V, 4.7 A at 60 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V. The 10 A at 230 V covers most industrial control loads; the 0.26 A at 600 V tells you it handles low-current signaling in higher-voltage panels. A built-in diode surge suppressor protects the coil circuit from back-EMF.
Mechanical and electrical endurance
Rated for 30,000,000 mechanical operating cycles typical. Maximum switching frequency at AC: 10,000 operations per hour. At DC, the switching interval is 38 to 65 ms.
