Scope
This standard mainly stipulates the terms and definitions, classification, characteristics, structure, and performance requirements of low-voltage intelligent phase selectors. It also specifies the tests and test methods used to verify compliance with the specified requirements. This standard applies to low-voltage intelligent phase selectors whose main contacts are used to connect circuits with a rated AC voltage of no more than 1000V, and which use microprocessors to control electromagnets and switch capacitors when the main circuit reaches zero.
