- Integrated fuse and contactor design reduces EV component count and system complexity.
- Validated fault interruption capability reaches up to 16 kA at 1 kV.
Integrated High-Voltage Protection for Electric Vehicles
The Sensata Technologies FaultBreak contactor introduces an integrated high-voltage switching and protection solution for electric vehicles, combining safety, compact design, and simplified battery system architecture.
Passive Fault Interruption Design
FaultBreak incorporates a passive resettable fuse function that interrupts faults without external electronic sensors. Validation testing confirmed fault clearing during repeated events up to 16 kA at 1 kV.
Dual Configuration for Added Reliability
For additional reliability, the Sensata Technologies FaultBreak contactor can operate in dual-contactor redundancy configurations.
Reduced Components and Improved Efficiency
Combining fuse and contactor roles in one assembly reduces component count by more than 50 percent.
Low contact resistance further limits thermal losses and improves efficiency.
