The Siemens 3RU5116-0HB00-0FE0 is an overload relay rated for 0.55 to 0.8 A, with a 1NO+1NC contact configuration, housed in a Size S00 frame, and designated Class 10 trip class. It is designed for direct mounting onto a contactor. The 0.55 to 0.8 A current range means this relay protects small motors or transformer primaries drawing under an amp. Size S00 is the smallest Siemens frame for these overloads, so it fits tight DIN-rail panels where every millimeter of gland-plate space counts. The 1NO+1NC contacts give one normally-open auxiliary for a run-permissive signal and one normally-closed for a fault alarm back to the PLC input card.
