The Siemens 3RB1262-0LB40 is an overload relay with an analog output, covering a setting range of 200 to 820 A and operating on 24 V DC. This is the part for protecting larger motor loads where you need a current signal back to the PLC or drive for monitoring or diagnostics — the analog output gives you a proportional 4-20 mA or 0-10 V (depending on wiring) that tracks the actual motor current, not just a trip flag. The 200-820 A window puts it squarely on medium-to-large induction motors, compressors, or pumps in the 100-400 kW range at 400 V.
