The Siemens 3RB1246-1PM40 is an overload relay with an analog output, covering a setting range of 1.25 to 6.3 A on a 220 to 240 V 50/60 Hz control supply. This is the part that sits between the contactor and the motor starter, providing adjustable thermal protection for small to mid-range induction motors. The analog output lets a PLC or drive controller read the motor current directly, eliminating a separate current transformer on the line side.
