NettetThe overload or thermal protection pickup (Ir) is set by using a multi-position dial. The default Ir pickup setting value is 0.4 x In (minimum dial value). The overload or thermal protection tripping range is 1.05–1.20 x Ir according to IEC/EN 60947-4-1 standard. The following table shows the preset values of the adjustment dial Ir in amperes ... The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. The different classes are defined by NEMA, Underwriters Laboratories (UL), and IEC standards.
