Preface

This textbook has been drawn up on the basis of the wide experience gained in the field of vocational training in the FRG and is intended for trainees of electrical engineering.

It is based on the fundamentals of low-voltage switchgear. In a didactically edited form it contains the necessary knowledge for this field of electrical engineering.

With the help of many figures and corresponding surveys as well as a clear and comprehensible textural representation the trainees are assisted in understanding the problems dealt with* Taking into consideration the unity of theory and practice the trainees can use this textbook as a working basis in theoretical vocational training and in practical vocational training. Taking into account the corresponding IEC recommendations the low-voltage switchgear explained is taken from FRG production, represents a selection and is to be assimilated to products existing in each case.
