動作理論と構造の特徴\ n ------------------------------------------- -------------------------------------------------- -------------------------------------------------- ----------------------------- \ n
GV2 circuit breaker is an integrated equipment which includes the functions of isolator,breakers,thermal relay,etc.It can effectively protect power system from malfunctions as overlaod,phase defect,temperature compensation,short-circuit,etc.
GV2 circuit breaker complies to GB14048.2,GB14048.4,IEC40947-2,IEC60947-4-1 standards.
GV2 structure:connected to mian circuit through thermal components,while motor suffers from overload,the bimetallic strip inside got heated up to trigger the circuit breaker to break off.
When motor suffers from phase defect,the bimetallic strip of this phase would cool down and recover its shape,by differential device's enlarging effect,circuit break would break off.While current reach the limit of instantaneous electromagnetic trip,magnetic core acts at once,forcing lever to cut off the current while driving operating module to trip,making circuit breaker to break off.
GV2 breaker is in consist of bottom foundation,contact support,arc-chute,insulating base,thermal-magnetic system(including instantaneous electromagnetic tripping unit,bimetallic strip,thermal components,etc.),differential device,curent adjusting device,operating module,product cover,push button and so on.
GV2 breaker adopts flip-over direct-acting type double contacts structure,contact bridge,contact support & arc-chute are installed in the bottom foundation,thermal-magnetic system,static contact,operating module,differential device,current adjusting device are iinstalled on base.There is a breaking test function,toggle the handle inside the "test" column according to the printed arrow to make sure the overload tripping function is reliable.

\ nアクセサリー\ n --------------------------------------------- -------------------------------------------------- -------------------------------------------------- --------------------------- \ n
6.1 Breaker can be equipped with undervoltage trip,shunt trip (shunt & undervoltage can't be equipped simultaneously.),auxiliary contact,etc,When voltage drops to 35%~70% of rated voltage,undervoltage trip shall act,voltage becomes lower than 35% of rated voltage,undervoltage trip would prevent breaker from switching on,voltage become higher than 85% of rated voltage,undervoltage trip shall secure that the braker switches on.
6.2 Shunt trip features
Shunt trip's trigger voltage is 70%~110% of rated voltage,thus effectively making the breaker switches off.
6.3 Accessory install position & dimension refer to below picture.
