This course provides a comprehensive understanding of IEC 60947-4-2, the international standard that specifies the requirements for semiconductor motor controllers, semiconductor motor starters, and AC semiconductor controllers and contactors for non-motor loads. It is designed to help engineers, testing professionals, certification specialists, and students understand the technical, safety, and performance requirements of this important IEC standard.
Throughout the course, you will learn the complete structure of IEC 60947-4-2, beginning with its scope, terminology, classifications, utilization categories, ratings, and construction requirements. The course then explores insulation coordination, creepage and clearance distances, protective measures, temperature limits, and electrical safety requirements essential for designing reliable and compliant products.
You will gain detailed knowledge of design verification and testing, including operating capability tests, thermal stability tests, overload capability tests, blocking and commutating capability tests, dielectric withstand tests, temperature-rise verification, EMC immunity and emission tests, routine verification, and short-circuit testing. The course also explains Type 1 and Type 2 coordination, conditional short-circuit current testing, and coordination with short-circuit protective devices.
