## General Notes 

1. For customers who can accommodate a vented device, contact Sensata Technologies for more information. 2. Current rating (both continuous and momentary) is dependent on bus bar size and customer specific application conditions. Consult with Sensata Technologies for specific details. 

3. Performance in application will vary based on customer environment and system isolation requirements. Validated at following conditions: 650 V, 15.5kA, 12 µH system inductance. Up to 850 V, 12kA, with 4 µH system inductance. For 1000V application above 3kA, contact Sensata engineering 

4. Clear time below 5kA can reach up to 4 ms max. IR after 8MW interrupt >1MΩ 

5. Insulation resistance is dependent on power level of max interrupt load and IR increases with reduced power levels or lower system inductance. IR after standalone short circuit may be below 0.5M at system inductance over 4uH. Performance when tested at system level will show improved IR post interrupt. 

6. Device can operate in higher ambient temperatures with derated current carry while below maximum terminal temperature. 

7. Measured on top of the bus bar at the bolted joint. Customer is responsible for ensuring this condition is met otherwise damage to device can occur. 

8. Sensata Technologies recommends orienting Z axis orthogonal to any mechanical shock pulses to ensure robust performance under load. Sensitivity is dependent on trip setting, consult with Sensata Technologies for more details. See photo for axis orientation. 

9. Performance depends on specific vibration profile and trip level, consult with Sensata Technologies for your specific requirements. 

10. For Automotive Applications please request technical workshop with Sensata Technologies Application Engineering.
