The • K circuit breaker of the General Electric Com-pany, now in use on all railway generator and feederpanels furnished by that company is very elaborately. worked out to meet the demand for something that willopen a heavy 500-volt circuit without soon destroyingitself. In principle it is as follows: The total current ofthe generator or feeder passes through the large verticalmagnet and across a bridge of flexible copper strips,which bridge is normally locked in contact with the con- ducting studs of the breaker. The magnet acts upon alever to trip this lock and a heavy spiral spring pullsaway the bridge when freed by the action of the magnet.(Jpposed to the armature trip lever of the magnet is atension spring which is carefully graduated by test andcan be so set as to allow the armature to trip only at adefinite magnet pull; this pull depends directly on theamperes in the circuit and the scale reading of the springis consequently marked in amperes. The tripping tensioncan be varied in a given instrument through a consider-able range and thus the breaker be adapted to variousrequirements. When a current of se
