ARC PLATE OF MAGNETIC CONTACTOR THAT HAS FUNCTION TO GUIDE ARC

摘要

PURPOSE: An arc plate of magnetic contactor is provided to improve arc extinction without increasing the size of the arc plate or the distance between electrodes. CONSTITUTION: An arc plate(A) includes a sidewall(10), a connection piece(20), and a guide protrusion(30). The sidewall is separated from each other at regular intervals. The connection piece connects both walls. The guide protrusion is protruded to a movable electrode(100) adjacent to the sidewall. The movable electrode includes a movable conductor(110) and a movable contact(120). A fixing electrode(200) includes a fixing conductor(210) and a fixing contact point(220).
