This standard specifies the technical requirements, test methods, inspection rules, marking and packaging requirements for terminal blocks in small and medium-sized asynchronous motor wiring devices. This standard is applicable to general-purpose small and medium-sized asynchronous motors (frame size 63~355) of 690V and below. It is also suitable for the connection of internal components of small and medium-sized asynchronous motors, but it is not applicable to small and medium-sized asynchronous motors with special requirements.
