Abstract
A circuit interrupter including an arc extinguisher which functions to arrest an arc that develops between electrical contacts. The circuit interrupter includes a permanent magnet coupled at opposite ends to two magnetically permeable pole pieces that are configured to drive or urge an arc into toward an arc extinguisher. The device allows for arc motivation due to the magnetic field without requiring the use of electrical power and allows for a rugged, light-weight design.
