- Scope
- This standard specifies the general rules and requirements for CJT1 series AC contactors whose main contacts adopt new copper-based silver-free electrical contacts, including: terminology; characteristics; normal operating and installation conditions; structural and performance requirements; characteristics and performance verification, etc. This standard applies to contactors with AC 50 Hz (or 60 Hz), rated voltage up to 380 V, and current up to 150 A. Contactors are mainly used to frequently connect and break circuits over long distances, and are combined with appropriate thermal relays or electronic protection devices to form motor starters to protect circuits that may be overloaded.
