SHUTTER HOLDING DEVICE FOR SWITCHBOARD

摘要

PROBLEM TO BE SOLVED: To obtain a shutter holding device which does not cause short circuit, even when a shutter in a switchboard drops onto the terminal conductor of a switch due to some trouble. SOLUTION: A dropping-down inhibiting member 23 which inhibits the dropping down of a shutter 24 arranged on the front face side of the main circuit breaking section 10 of a switchboard in a closing direction is attached to the terminal conductor 14 of a switch 5. The member 23 is protruded from the switch 5 side so that the member 23 may be extended toward the circuit breaking section 10 from a position below the shutter 24 in the vertical direction, when the switch 5 is joined with the circuit breaking section 10.
