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