Product description

The Siemens 3RH1122-1AB00 is a SIRIUS contactor relay featuring 2 normally open (NO) and 2 normally closed (NC) contacts. It operates on 24V AC (50/60 Hz) and utilizes screw terminals for easy connection. This part is noted as phased-out, with the SIRIUS 3RH2 series being its successor, specifically the 3RH2122-1AB00 as the preferred replacement.

This contactor relay is suitable for control circuits in industrial automation, motor control, and power switching applications where reliable switching of auxiliary circuits is required. Its compact size (S00) makes it ideal for panels with limited space. The phased-out status indicates a need to consider the newer generation for long-term projects.
