Siemens 3RH1122-2AP00 Auxiliary Contactor Relay

Siemens 3RH1122-2AP00 Auxiliary Contactor Relay is a compact control relay featuring two normally open and two normally closed auxiliary contacts (2NO+2NC) powered by a 230 V AC coil suitable for 50/60 Hz operation. Built on the S00 frame size, it uses spring-loaded terminals for secure wiring and supports vertical mounting with the option to tilt ±22.5° and rotate up to 180° to fit a variety of panel layouts. The auxiliary contacts are rated for AC-15 operation, handling up to 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V, making it ideal for signaling, interlocking, and feedback in control circuits without switching motor loads. This Siemens unit is designed to complement main contactors in automation assemblies, providing reliable auxiliary signaling within a compact, space-efficient package.
