<p>The contactor has a magnet arrangement generating electromagnetic force on electric arcs (8), which are produced when contacts (21, 22, 31, 32) are opened. The magnet arrangement includes permanent magnets (51), and a moving contact bridge (4) includes a section (42), which is arranged between a guide (9) and one of the contacts. The section is formed in such a manner that an opening is provided in the contact bridge for one of the electric arcs, which is produced at the contact to pass through the opening in the direction of the movement direction of the contact bridge.</p> |
