| 发明名称 | Circuit breaker shock absorber apparatus, assemblies, and methods of operation | ||
| 摘要 | Embodiments disclose a circuit breaker shock absorber apparatus configured to absorb impact due to blow-off of one or more circuit breaker contact arms. The circuit breaker shock absorber apparatus has a base directly or indirectly coupled to a circuit breaker housing and an absorber body comprising a damping material having a tangent delta at 10% strain and 10 Hz and at room temperature of greater than about 0.45, and a durometer of less than about 60 per ASTM D2240 Type A. Circuit breaker shock absorber assemblies and methods of operating the breaker shock absorber assemblies are provided, as are other aspects. | ||
