Abstract
At the present time, the bureau of Ships uses separately mounted-magnetically or thermally-actuated relays to protect a-c motors from overload, single-phase, and locked rotor conditions. With the advent of silicone-insulated motors requiring different overload relay characteristics, the development of relays operating on the actual motor winding temperature was undertaken.
