Abstract

Disclosed is a spring charging device (100) of air circuit breaker mounted with at least one or more micro switches and a switch lever (140) for turning on/off the micro switches capable of compressing the spring (11) and notifying completion of the compression of the spring when the charging is completed, thereby enhancing the efficiency in operation of the air circuit breaker by a user (an operator).
