    Glossary Trip class (CLASS) The trip class of an inverse time-delay overload relay specifies the maximum tripping time from cold at a particular load. The trip class number (e.g. CLASS 10A) represents the maximum permissible tripping time in seconds when the 3RM1 motor starter is subjected to a symmetrical 3-pole load from cold with 7.2 times the current setting (IEC 60947-4-1;...
