JB/T 8980-2007 (English Version) PDF

Scope: This standard specifies the basic rules and requirements for rotary AC contactors (hereinafter referred to as contactors), including terminology, characteristics, normal operating and installation conditions, structural and performance requirements, test methods and rules for verifying characteristics and performance requirements, and signs, etc. . This standard is applicable to contactors in power lines with AC 50Hz and rated voltage up to 1000V AC. It is mainly used in electrical equipment such as cranes in metallurgy and steel rolling enterprises to make and break circuits over long distances, and as a frequent starting and stopping device for AC motors. and reverse connection, etc.
