Siemens 3RH1122-1AP60 Three-Phase Contactor Relay

Siemens 3RH1122-1AP60 is a Sirius four-pole contactor relay with a 220–240 V AC coil and an auxiliary contact arrangement of 2 normally open (NO) and 2 normally closed (NC) contacts. This size S00 device uses screw-terminal connections and is designed for compact installation in control panels, with insulation voltage up to 690 V and front IP20 protection. The coil operates on 50 Hz at 220 V and 60 Hz at 240 V, making it compatible with common European control circuits, and the assembly supports reliable signaling and interlocking in automation schemes. It offers a lengthy mechanical life, typically around 30,000,000 switching cycles for the contactor function, and can be mounted on standard 35 mm DIN rails or on a fixed surface via a screw mount. Operating ambient temperature ranges from -25 to +60 C (storage/transit ratings extend to -55 to +80 C), ensuring dependable performance in typical industrial environments. Suitable for Siemens control architectures, this 3RH1122-1AP60 provides a compact, rugged solution for switching and isolating circuits that require both NO and NC contact signaling in a single module.
