Abstract
A manual trip control method and arrangement is provided to manually trip a plurality of circuit interrupters. Specifically, where the circuit interrupters include magnetic-actuator-driven vacuum interrupters including permanent magnets that hold the contacts of the circuit interrupter in the closed position via a plunger, a first of the circuit interrupters is manually tripped via movement of the plunger. To operate the remaining circuit interrupters to trip open, the voltage generated in the magnetic actuator of the first circuit interrupter is coupled to the magnetic actuators of the remaining circuit interrupters for tripping thereof.
