The Triton 03313 Electric Breakaway Kit activates your electronic brakes if your trailer becomes disconnected from your vehicle while towing. Even if your coupler disconnects and your safety chains fail, the Triton 03313 Electronic Breakaway system will prevent a runaway trailer situation. Remember that most states require trailer breakaway systems if the trailer weighs more than 3,000 lb. This kit also features a compact, rechargeable, sealed and maintenance-free battery with box. Breakaway switch included.
