Different Current Ratings provide selection option depending on varied load conditions. Offered in different pole configurations based on system requirement. Overload Setting is Fixed and Short Circuit Setting is minimum 10 times of Rated Current.
They are able to fully verify that a machine tool is operating within tolerance, before critical machining operations are carried out on high-value components. Traditional methods of verification machine tools require.
A full verification would then only be performed if errors were observed in the parts they produced. In the pursuit of improved quality and zero-defects, many manufacturers now perform regular checks and recalibrations. This means that checks may be performed weekly and Verification annually. This is a major step forward, although a significant risk of non-conformance remains.
