<p>PURPOSE: An extinguishing device of a low voltage breaker is provided to improve a short blocking capacity by forcedly blocking an arc path before an arc is cooled. CONSTITUTION: A first stator(200) is formed in a first fixed contact point(210). A second stator(100) is formed in a second fixed contact point(110). A shaft(500) moves a second mover(400) and is operated by a handle(600). A first mover(300) is formed in a first moving contact point(310) and a second moving contact point(320). An extinguishing device(700) blocks an arc path before the arc is cooled. An arc blocking layer(730) includes an insulation unit and a horizontal unit with a returning spring(740).</p> |
