FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering. Shutter for switchgear comprises fixed electric contacts and automatic circuit breaker having movable electric contacts. The shutter comprises panel element movable between non-protective position, wherein the panel element ensures connection of movable electric contacts with the respective fixed electric contacts, and protective position, wherein the panel element prevents connection with the fixed electric contacts. Driving lever facilities are made to actuate the above panel element upon movement of the movable electric contacts. A cam-profiled part at the driving lever facilities is intended for interaction with pins moving together with the movable electric contacts. The cam-profiled part and pins facilitate disconnection of driving facilities from pins during functioning of the shutter.
EFFECT: increased reliability and safety efficiency and simplification of the design and decrease in dimensions.
