The Siemens SIRIUS 3RT5936-1TR00 is a surge suppressor built for DC control circuits, specifically a diode combination without LED rated at 24 V DC. It connects at the bottom of the contactor or relay it protects, and the design uses diode assemblies to clip the inductive kick from the coil when it de-energizes — that's what keeps the back-EMF from welding contacts or taking out the PLC output driving it. For anyone commissioning a panel with SIRIUS contactors, this is the plug-in snubber that goes on the coil terminals; no separate wiring to the control circuit, just snap it on.
