1. For 2017-2022 Tesla Model 3/Y
2. Original part number: 1064689
3. Circuit pins, mounting holes, and electrical parameters are fully compatible with the original vehicle parts, requiring no wiring modifications and allowing for direct, non-destructive replacement.
4. Instantly and decisively cuts off the high-voltage circuit in extreme abnormal situations such as severe collisions, short circuits, or overloads, protecting the battery core and the entire vehicle from secondary electrical damage.
5. The casing is made of flame-retardant, high-temperature resistant, high-grade insulating engineering materials. The internal alloy fusing mechanism has been precisely tuned, possessing excellent vibration resistance and electromagnetic interference (EMI) resistance, ensuring no malfunction under various complex and harsh driving conditions.
6. When the vehicle's high-voltage system locks up due to safety protection triggering, or when the original vehicle's cut-off circuit breaker blows due to an accident or aging, this product is a crucial replacement part for restoring the vehicle's high-voltage power supply system, offering extremely high cost-effectiveness.
7. No complicated tools required, allowing you to easily complete quick in-situ installation.
