Electric circuit breaker arc chute composition |
摘要 |
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 three-layer configuration wherein the two outer layers have excellent arc extinguishing properties while the inner layer has good mechanical support strength.
