NOTE: Average power dissipation of transients not to exceed 2.0W.
1. Peak current applies to applications rated up to 115 V . Peak current is 30kA for applications greater than 115V .
2. Peak current applies to applications rated up to 123V . Peak Current is 30kA for applications greater than 123V .
3. Peak current applies to applications rated up to 132V . Peak Current is 30kA for applications greater than 132V .
4. Peak current applies to applications rated up to 97V . Peak Current is 30kA for applications greater than 97V .
5. 40kA capability depends on applications rated up to 97Vrms. 30kA applies if >97 Vrms.
