摘　　要：介绍了附录L中不满足IEC60947-2标准正文规定的过电流保护要求的断路器,该种断路器能配装各种辅助装置(附件),如分励、欠电压脱扣器,它不能作为电路的保护,但可在短路条件下脱扣,以保护自身,以用作隔离器。It introduces the circuit breaker which can not meet the requirements for overload current protection requlated in the text of IEC60947-2 standard, such kind of circuit breaker can be assembled into various kinds of auxiliary devices(accessary), such as excitation division, voltage lack tripper, it can not be taken as circuit protection, but can be tripped under short circuit conditions so as to protect itself to be used as an isolater.
