3RH1122-2KF40 SIEMENS

The 3RH1122-2KF40 is a contactor relay manufactured by Siemens, designed for switching electrical circuits in industrial control applications. It features a configuration of 2 normally open (NO) and 2 normally closed (NC) contacts, providing flexibility in circuit design. The relay operates on a 110 V DC control voltage, with a working range of 0.7 to 1.25 times the rated voltage, ensuring reliable operation even with voltage fluctuations. An integrated varistor provides surge protection, safeguarding the relay and connected equipment from voltage spikes. The relay utilizes spring-type terminals for quick and secure wiring connections, reducing installation time and improving reliability. It comes in size S00, a compact design suitable for space-constrained applications. Please note that the 3RH1122-2KF40 is a phased-out product, and the recommended successor is the SIRIUS 3RH2122-2KF40. The successor 3RH2122-2KF40 offers enhanced features and performance compared to the older model. For new installations and replacements, it is advisable to use the SIRIUS 3RH2122-2KF40 to ensure compatibility and long-term availability.
