Abstract
A current limiting circuit breaker having a pair of separable contacts closely spaced for electrodynamic repulsion upon the occurrence of a short circuit overload condition utilizes an arc chute to cool and extinguish the arc that occurs when the contacts become separated. The arc chute contains a plurality of metal arc plates supported by side plates which also assist in cooling and extinguishing the arc. The side plates are formed from a suspension of wollastonite fibers within a melamine resin matrix. The wollastonite provides good mechanical strength and temperature-resistance properties while the melamine provides a continuous source of arc-quenching gaseous molecular compounds.
