INTERRUPTER CONTROL AND PROTECTIVE MODULE Russian patent published in 2006 - IPC H01H73/00 

FIELD: electrical engineering.

SUBSTANCE: proposed module is designed for controlling and protecting multipole low-voltage interrupter that has base, control electromagnet, and circuit breaker actuating movable contacts to connect and disconnect poles. This removable module has electronic card incorporating processing unit, control gear, and protective gear designed to activate electromagnet and circuit breaker in response to control signal and to OFF-operation signal arriving from processing unit. The latter can turn off electromagnet control signal in case protective gear fails to perform its functions. Servo system is inserted between electromagnet control gear and circuit-breaker control gear and centralized electronic means are used for processing.

EFFECT: enhanced operating reliability of multifunctional interrupter.
