It is designed for switching control circuits in motor starter and automation panels, where the contact configuration and coil voltage must match the PLC or relay output driving it. ## Contact ratings across the voltage range The contact current rating varies significantly with the switched voltage: at 24 V it handles 10 A, at 230 V AC it also carries 10 A, but at 600 V the rated current drops to 0.26 A. This derating reflects the arc energy at higher voltages — for a 480 V control circuit the 3 A rating at 400 V is the relevant figure, while a 24 VDC pilot duty stays within the 10 A envelope. ## Panel integration and mounting flexibility The relay measures 73 mm deep by 45 mm wide by 57.5 mm high and mounts via screw or snap-on onto a 35 mm DIN rail. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, so it fits into tight enclosures or angled sub-panels without forcing the wiring layout.","metaTitle":"Siemens 3RH2122-1TP00-0RA0 SIRIUS Contactor Relay, 230 V AC","metaDescription":"Siemens 3RH2122-1TP00-0RA0 SIRIUS auxiliary contactor relay, 2 NC+2 NO, 230 V AC 50/60 Hz, Size S00.
