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 two-layer configuration wherein the first layer has excellent arc extinguishing properties while the second layer has good mechanical support strength. The side plates are oriented such that the first layers face the contacts.
