The Siemens 3RU1136-4FB0 thermal overload relay is electrically and mechanically optimised to the 3RT103 contactors such that, in addition to individual mounting, they can also be directly mounted onto the contactors to save space. The main and auxiliary circuits can be connected in various ways, including the use of Cage Clamp terminals. When the overload relay has been connected, it can be tested for correct functioning using a TEST slide. In addition to the TEST function, the 3RU1131 thermal overload relay is equipped with a STOP function.
