JB/T 8591.2-2007 (English Version) PDF

Scope: This part of JB/T 8591 specifies the basic requirements for CJ26 and CJ28 series AC contactors, including terminology, characteristics, normal working and installation conditions, structural and performance requirements, test items and test methods, etc. Contactors are mainly used to connect and break circuits in power systems with AC 50Hz (or 60Hz), rated voltage up to 660V, currents up to 32A for CJ26 series contactors and up to 475A for CJ28 series contactors, and are used with appropriate thermal relays or electronic Protectors are combined into motor starters to protect circuits where overloads may occur.
