 DSTU EN 60947-8:202_ (EN 60947-8:2003, IDT; IEC 60947-8:2003, IDT) specifies the rules for control devices that perform switching functions after the temperature sensors are incorporated in rotating electrical machines according to IEC 60034-11, for industrial applications. These specified rules are applicable to a system consisting of a thermistor sensor with a positive temperature coefficient (PTC) having certain characteristics and an associated control device. These rules specify the characteristics of the connection of this particular thermistor sensor with a positive temperature coefficient and an associated control device (designated as “class A sensor” and “class A control device”) when used in thermal protection systems.
