Document Type and Number:

Japanese Patent JP4567772

Kind Code:

B2

Abstract:

Disclosed is an apparatus for indicating a closing operable state for an air circuit breaker and an air circuit breaker having the same. The apparatus for indicating a closing operable state for the air circuit breaker comprises a micro switch installed at a switching mechanism providing a driving force for switching contactors, provided with a lever extended into the switching mechanism so as to receive the driving force, generating and outputting an electric signal for indicating that the air circuit breaker is in a closing operable state, and provided with a signal transmitting terminal for transmitting the electric signal to a remote place, and an on coupling pressing the lever of the micro switch so that the micro switch generates and outputs the electric signal only when a closing spring for providing elastic energy for switching the contactors charges elastic energy and the air circuit breaker is opened.
