FIELD: electrical engineering.
SUBSTANCE: invention relates to components of switching hardware, particularly DC switch. DC switch independent magnetic blow-out device on permanent magnets consists of permanent magnets and magnetic core. Every magnetic pole incorporates U-like horns. One pole of magnetic core is fitted between bifurcated horn parts of every electric pole, while another one is located at the bottom and aside of aforesaid U-like horns.
EFFECT: higher reliability of arc control due to DC arc blow-out in preset direction at whatever arc current direction.
