Product Description
Used OEM High-Voltage Battery Safety Replacement
This used OEM pyrotechnic disconnect is designed for Tesla Model S high-voltage battery service applications where the original disconnect unit has failed, triggered, or requires replacement during repair. It is matched to OEM Part No. 1111313-00-F and positioned as a practical OEM replacement for qualified HV battery service work. Tesla service documentation identifies this component as a pyrotechnic disconnect rated at 2000A, confirming that it is a high-voltage battery safety component rather than a standard low-voltage fuse.
Built for Professional HV Battery Repair
This is a safety-related electrical component used within the high-voltage battery system. It is best suited for professional repair scenarios involving HV battery service, fault diagnosis, triggered disconnect replacement, or post-incident restoration. Tesla service information places this part within HV Battery Electrical Components and treats replacement as a qualified high-voltage repair procedure.
OEM Part Number Clarity Matters
For high-voltage system parts, correct part number matching is essential. This product is identified by OEM Part No. 1111313-00-F, which is the key reference buyers and technicians should verify before ordering. Public market listings also use this exact OEM number for Model S pyrotechnic disconnect applications.
A More Cost-Effective OEM Alternative
Compared with high-priced new OEM inventory, a used OEM disconnect can be a more practical repair option when the correct part number and application are confirmed. Public listings show a wide pricing spread between used OEM and new OEM inventory, which supports positioning this product as a cost-effective OEM replacement for repair-focused buyers.

Installation Information
Installation Location
Necessary Installation Tools
- High-voltage insulated gloves (rated ≥ 1000V)
- Torque wrench (with 12Nm and 7.5Nm calibration)
- Insulated socket set
- ESD anti-static wristband
- Flat-head screwdriver (insulated)
Step 1
Power Off Safely
Turn off the vehicle, disconnect the 12V battery negative terminal, wait 5 minutes to discharge residual high-voltage electricity. Wear insulated gloves and ESD wristband.
Step 2
Remove Cover
Locate the high-voltage fuse cover (front trunk or under chassis), remove 6-9 fixing bolts, and take off the cover carefully.
Step 3
Take Out Old Fuse
Disconnect the fuse connector, unscrew 2 fixing nuts (12Nm) with an insulated wrench, and take out the old fuse (do not reuse).
Step 4
Install New Fuse
Check the new fuse (1111313-00-F), align with the slot, push firmly until the connector is fully seated. Ensure the arrow on the fuse points to the rear of the vehicle. Tighten the 2 nuts to 12Nm.
Step 5
Reset & Test
Reinstall the cover with new bolts (torque to 7.5Nm), reconnect the 12V battery. Start the vehicle and check for no error lights.
Notes & Safety Warnings
- High Voltage Risk: Only qualified electricians (with low-voltage electrician certificate) can operate. Never work without power-off.
- One-Time Use: The fuse is disposable; do not reuse after activation.
- Arrow Direction: The arrow must point to the rear of the vehicle; wrong direction causes system failure.
- Torque Requirement: Tighten bolts to the specified torque (12Nm/7.5Nm) to avoid short circuit or damage.
- Safe Environment: Operate in a dry area; avoid rain or humidity.
