Description
External sacrificial fuse kit for Tesla vehicles with a PTC cabin heater (Model S, Model X, and Model 3).
Includes:
• One 25A aR high-speed semiconductor fuse
• One fuse holder
Not included: PTC heater, wiring, or connectors.
Adds a lower-amperage fuse in the PTC circuit so a heater failure is less likely to blow the main HV fuse. Especially useful on Model S & X where main fuse replacement is difficult due to requiring the high voltage battery to be removed from the vehicle, saving potentially $1000+ by not having Tesla replace the main PTC fuse.
Notes:
• DIY kit for owners familiar with Tesla HV systems.
• Requires proper HV safety procedures. Install at your own risk.
• Fuse brand and exact holder may vary; parts meet the necessary ratings and requirements.
• Confirm PTC heater and circuit on your vehicle before use.
