Scope

This part of GB/T 14048 applies to semiconductor controllers and starters for AC motors intended to be connected to circuits with a rated voltage not exceeding AC 1000V, which may have a series mechanical switching device. This standard specifies the characteristics of semiconductor controllers and starters for a.c. motors with or without bypass switching devices when used. Semiconductor controllers and starters for AC motors covered by this standard are generally not intended for breaking short-circuit currents. Therefore, appropriate short-circuit protective devices should be used (see 8.2. This appendix specifies the test methods for verifying the performance of the overload protective devices in the starter when the starter is used in conjunction with the SCPD. C.2 Overview and definitions K.1.1 General requirements The appendix specifies the extended functions of electronic overload relays that are not directly related to overload protection. The functions of overload relays not specified in this part shall meet the requirements of relevant standards (such as IEC60255 series, IEC60947 5 series) that include this function. This appendix only Suitable for electronic overload relays used in AC circuits. K.1.2 Residual current protection
