Abstract

PURPOSE:To make easier the attachment of shutter to board frame by unitizing shutter device. CONSTITUTION:A shutter device, provided with a driving gear to drive the shutter plate 6 designed to close or open the disconnected through hole of the disconnected partition plate 3 in an interlocking way with the drawing or insertion movement of the breaker 2, is unitized and then fastened secruely to the inside of the board frame 1 in common to the main circuit disconnected portion 20 by attaching the shutter guide 5 to the frame. Thus, the attachment of the shutter device can be performed easily without specific improvement for electric machine and board frame to be housed in the room of electric machine. Also, since the attachment is common to the fitting portion of the fitting plate 21 for the main circuit disconnected portion, electric machine can be interchangeably housed regardless of the presence of shutter device.
