绕组继电保护及PTC热敏电阻

        It is a Winding Protection relay based on thermistor (PTC) . It offers protections against Over heating of the windings of pumps, motors, transformers, alternators etc. & sense the temperature with the help of PTC thermistor. It can be used with single or triple PTC & also with 6 or 9 PTCs as a special case. It can used for AC/DC motor, generator, transformer, winding protection against over heating of SCRs & Bus Bars.
