More Information
Summary:A current limiting circuit breaker mechanism having two pairs of separable contacts closely spaced for electrodynamic repulsion upon the occurrence of a short circuit overload condition utilizes a pair of arc chute assemblies to cool and extinguish the arc that occurs when the contacts become separated. The arc chute assemblies contain a plurality of arc chute plates supported by side supports. The arc chute plates are aerodynamically designed to facilitate the easy flow of the arc plasma gases into and out of the chute and provide minimal reflection of the arc plasma wave against the contact arm.
