- Scope
- This standard specifies the type parameters, technical requirements, test methods and inspection rules for starting components of small single-phase asynchronous motors. This standard is applicable to starting components used to disconnect the auxiliary winding circuit in single-phase asynchronous motors with rated voltage 250V and below, rated frequency 45~65Hz, and output power 5.5kW and below. It mainly includes: centrifugal switch and voltage sampling type starter. Switch, current sampling starting switch, temperature sampling type starting switch. This standard does not apply to ordinary voltage relays and current relays.
