Protection of equipment from overheating

In article protection with use of the relay which reacts to temperature of the electric motor irrespective of the overheat reasons is considered. Relay possibilities are listed. Timing diagrams of work of the relay are given. The scheme of inclusion of the relay is developed for the control of temperature of three engines simultaneously at the expense of use of three recorderes, the detailed description of the scheme is made.
