3RH1122-1AB00

The Siemens 3RH1122-1AB00 contactor relay is designed for reliable control in industrial environments. It operates at a control voltage of 24V AC, suitable for 50/60 Hz applications. The relay features a contact arrangement consisting of 2 normally-open (NO) and 2 normally-closed (NC) contacts, allowing for flexible configuration according to operational needs.

This unit supports an impressive insulation voltage of 690V, effectively relevant under pollution degree 3 conditions. Furthermore, it withstands surge voltages of up to 6 kV, enhancing its resilience against transient spikes in electrical systems. With an IP20 protection rating, the relay is intended for indoor applications where physical contact with the device is minimized.

The relay also boasts robust shock resistance characteristics, rated at 10g for 5 milliseconds and 5g for 10 milliseconds, ensuring reliable performance even in the presence of vibrations or impacts. Designed for longevity, it features a mechanical lifespan estimated at 30 million cycles, making it suitable for repeated operations in high-demand environments.

Regarding current ratings, the 3RH1122-1AB00 can handle a maximum current of 6A for AC-15 applications at 230V, as well as 10A for DC-13 applications at 24V. To protect against short circuits, it requires a 10A gL/gG fuse. This relay can be mounted using either screw or snap-on methods, depending on the installation needs, while its compact dimensions—57.5 mm (height) by 45 mm (width) by 72 mm (depth)—allow it to fit easily within control panels. The device operates effectively within a temperature range from -25°C to +60°C.
