Motor overload symbol
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 ...
