The FaultBreak contactor from Sensata Technologies is a high-voltage switching and protection device for electric vehicle power systems that combines contactor and fuse functions in a single component. The device provides passive resettable fault protection and is validated to interrupt fault currents up to 16 kA at 1 kV while maintaining low contact resistance for reduced power loss. Designed for EV platforms requiring high-voltage safety and compact architectures it helps reduce component count and system complexity compared with separate fuse and contactor solutions.
