Selection Notes

The 2 C/O contact arrangement gives two isolated switching paths from a single 230 V AC coil, useful where one contact drives a contactor coil and the second feeds an indicator or interlock circuit. The lockable test button allows local forcing during commissioning without energizing the coil, and the cylindrical pin shape distinguishes it from the flat-pin RPM series for socket compatibility. Choose the 1 C/O RPM series instead when only a single switching path is needed. The 184-253 V AC operating window covers normal mains tolerance without a separate voltage-monitoring relay.
