AEG SH04 Control Relay

The AEG SH04 Control Relay is a compact, four-pole mini relay from the AEG MOTOR CONTROL SH04 family, designed to switch control circuits in panels and automation equipment and built with screw clamp terminals for fast, secure wiring, with 50/60 Hz operation to fit typical industrial control schemes. The SH04 family spans several variants—SH04.22, SH04.31, SH04.40, and SH04.40-A (relay/socket)—offering different contact configurations and, in some models, plug-in sockets for quick field replacement; other models provide 24 V DC coils and load voltages up to 230–400 V AC depending on the exact configuration. Current ratings are model-dependent, with listings showing ranges that include around 4 A to 16 A for AC loads, and some SH04 variants are designed to integrate auxiliary contacts to extend signaling or interlocking capabilities. Typical applications include control panels for motors, valves, or solenoids, where a compact relay is needed to energize or monitor auxiliary circuits, and the availability of mounting sockets helps simplify service and maintenance.
