Learn how FaultBreak, an innovative resettable, passive fault protection technology, is reshaping high voltage EV system design. This webinar explores an alternative to traditional single use protection devices, showing how engineers can clear high magnitude fault currents while reducing system cost, weight, and architectural complexity and improve safety and serviceability.
Overview
As electric vehicles (EVs) move toward higher voltage and more efficient electrical architectures, conventional protection strategies based on fuses and contactors are increasingly strained. Challenges such as nuisance trips, single use protection devices, and layered redundancy drive added cost, weight, and vehicle downtime.
This webinar examines these limitations and introduces FaultBreak, an innovative fault clearing contactor designed to simplify and modernize high voltage fault protection. Attendees will gain insight into the engineering principles behind passive and active fault clearing, and how FaultBreak enables resettable operation that improves serviceability, reduces false triggering, and streamlines system integration.
Using validation results up to 16 kA at 1 kV, the session compares traditional contactor plus fuse designs with a FaultBreak based approach. Protection strategies are evaluated across safety performance, thermal behavior, cost, and system complexity. Participants will leave with a practical framework for specifying scalable, adaptable fault protection that lowers component count, reduces losses, and supports the next generation of EV platforms.
