Siemens 3RF2950-0GA13 is an extended load-monitoring module for the 3RF safety-relay family, designed to monitor currents up to 50 A. The 0GA13 variant is intended for line voltages in the 110–230 V range and provides load monitoring for devices driven by semiconductor relays or contactors. It is rated for ambient temperatures up to 40 °C. Used in safety circuits, this module monitors the current through connected loads as part of the Siemens 3RF safety ecosystem.
