摘要： A circuit interrupter of the type including an arc chute and separable contacts between which an arc may be drawn is provided with flash plates. The plates are disposed at either side of the region in which an arc forms and serve to protect the adjacent interrupter housing, while assisting in channeling the arc into the arc chute. The flash plates are formed of a ceramic material and are provided with a plurality of grooves running the direction generally transverse to the direction of the arc.

摘要： An overload relay, and an overload relay control circuit power source are disclosed herein. The overload relay includes an electronic trip circuit, a contactor such as a three-phase contactor, a current transformer associated with each power conductor coupled to the contactor, and a transformer associated with the contactor. The current transformers are coupled to the control circuit which controls the supply of power to the solenoid of the contactor based upon the level of current flowing in the power conductors connected to the contactor. The solenoid of the contactor is connected to at least one power conductor and maintains the contacts closed when the solenoid is energized. The transformer is magnetically coupled to the windings of the solenoid and produces the power required by the control circuit when the solenoid is energized and the contacts of the contactor are closed.

摘要： Means for causing the properly-polarized one of a pair of series-connected DC contactors to open before the other, depending upon the direction of load current flow. Load current is caused to link the magnetic circuit constituted by a contactor coil, frame and armature; with current flowing in a first direction, the linking has an additive effect, strengthening the MMF in the magnetic circuit. When current flows in the opposite direction, the MMF is weakened which allows the contactor to open more quickly.
摘要翻译：根据负载电流流动的方向，使一对串联的直流接触器中适当极化的一个直流接触器彼此打开的装置。使负载电流连接由接触器线圈，框架和电枢构成的磁路; 当电流沿第一方向流动时，连接具有附加效应，加强了磁路中的MMF。当电流沿相反方向流动时，MMF被削弱，允许接触器更快地打开。
