Abstract

A CIRCUIT BREAKER COMPRISES A PAIR OF BREAKER CONTACTS (31,32) DISPOSED IN A MAIN CURRENT PATH EXTENDING BETWEEN A LINE TERMINAL (20A) AND A LOAD TERMINAL (20B). THE BREAKER CONTACTS ARE COMPOSED OF A FIRST CONTACT (31) AND A SECOND CONTACT (32). AN ELECTROMAGNETIC RELEASE DEVICE IS PROVIDED TO FORCIBLY DISENGAGE THE SECOND CONTACT (32) FROM THE FIRST CONTACT (31) UPON DETECTION OF AN EXCESS CURRENT FLOWING THROUGH THE MAIN CURRENT PATH. THE RELEASE DEVICE COMPRISES A COIL (51) INSERTED IN THE MAIN CURRENT PATH AND A PLUNGER (54) SURROUNDED BY THE COIL. THE PLUNGER IS MAGNETICALLY CONNECTED TO THE COIL THROUGH A YOKE (52) WHICH IS OF A GENERALLY V-SHAPED CONFIGURATION HAVING A BASE MEMBER (52C) AND A PAIR OF SIDE MEMBERS (52A,52B) AT OPPOSITE ENDS OF THE BASE MEMBER. A PAIR OF OPPOSED FIRST AND SECOND ARC .RUNNERS (71,52C) ARE DISPOSED TO GUIDE AN ARC, WHICH DEVELOPS BETWEEN THE BREAKER CONTACTS UPON SEPARATION THEREOF, IN A DIRECTION AWAY FROM THE BREAKER CONTACTSBY AN ELECTROMAGNETIC FORCE ACTING ON THE ARC IN A MAGNETIC FIELD PRODUCED BY A RESULTING ARC CURRENT. THE FIRST ARC RUNNER (72) IS ELECTRICALLY CONNECTED TO THE FIRST CONTACT (31) AND EXTENDS AWAY THEREFROM TO GIVE AN EXTENSION (71C), WHILE THE SECOND ARC RUNNER (52C) IS ELECTRICALLY CONNECTED TO THE SECOND CONTACT (32) AND EXTENDING AWAY THEREFROM. THE YOKE (52) IS DISPOSED TO BE ELECTRICALLY CONNECTED TO THE SECOND CONTACT (32) AT THE SIDE MEMBER (52A) ADJACENT TO THE SECOND CONTACT (32). THE BASE MEMBER (52C) EXTENDS IN OPPOSED RELATION TO THE EXTENSION (71C) SUCH THAT THE BASE MEMBER (52C) ITSELF DEFINES THE SECOND ARC RUNNER. (FIG. 9)
