Chain breakers (thermal relays) - the general information

Thermal relays serve for protection of such components as electric drives of lowering lifting of glasses, door locks and adjustment of provision of head headlights. Some of breakers of a chain are placed in the assembly block of safety locks. Return of thermal relays to an initial state on some models is carried out automatically, i.e. at emergence of an overload in a chain the thermal relay is instantly disconnected, then, after cooling, reverts to the original state. If return of a contour into position does not happen, it is necessary to make its check immediately. Normal functioning of the thermal relay confirms serviceability of a contour. Some of breakers are equipped with buttons for manual compulsory return to an initial state.
