Document Type and Number:
Japanese Patent JP4193158
Kind Code:

Abstract:
A conductor housing (16) has a pair of stationary contacts (18). Movable contact carrier (12) has movable contacts (20). Magnetic components (26,30) are movably located near contact (20) and rigidly mounted on the carrier, respectively. Magnetic force caused by fault current drives the magnetic components to attract mutually by which movable and stationary contacts are separated. An independent claim is also included for the contact weld preventing method.
