Title:
SWITCH UNIT WITH INSULATION SCREEN TO BE INSERTED BETWEEN CONTACTS AT BREAKING
Document Type and Number:
Japanese Patent JPS61153908
Kind Code:
A
Abstract:
A switch in which a screen inserted between the contacts shears the opening arc. The screen is associated with a sheath that surrounds a contact support and slides on the latter when the gas pressure it is subjected to causes it to move at a velocity which is a function of the energy of the arc. The switch is applicable in particular to protective apparatus designed to limit fault current or breaking devices in which steady-state current is fairly high.
