Description
Summary:The article studies the dependences of active power losses in contacts and contact systems of circuit breakers, contactors and magnetic starters on the main parameters of electrical equipment. Models of functional dependences of active power losses on nominal current for low-voltage switching devices of some manufacturers are developed. Approximation functions of these characteristics have been compiled and the value of determination coefficient of the obtained functions of active losses and approximation error have been calculated. Graphical dependences of the investigated parameters of low-voltage equipment are presented.
