The GT Battery Isolator from CARTEK is a very small and highly reliable alternative to the traditional mechanical master-switch and has been designed to overcome all of the problems and restrictions associated with mechanical and electro/mechanical safety cut-outs. When fitted to a race car our Solid State Battery Isolator simultaneously isolates the battery and kills the engine immediately when triggered in accordance with FiA safety regulations.
Typical Applications:
The CARTEK Battery Isolator GT is designed to be used on a wide variety of race and rally cars - up to mildly tuned V8 engines.
Not suitable for Electric or Hybrid vehicles.

Small + lightweight design (120 grams)
Fully protected 40 Amp Engine Stop Output
Overcurrent + Overtemperature protection built in
Integrated status LED for diagnostic purposes
Totally sealed against water and dirt
Completely resistant to shock and vibration
Description
All CARTEK Battery Isolators are designed to perform two functions in accordance with FiA motorsport safety regulations. These are:
1) Stop the Engine from running, 'Kill'.
2) Disconnect the Battery from ALL electrical systems, 'Isolate'.
The 'Engine Stop' function is implemented by disconnecting power to the ECU or Ignition circuit - forcing the engine to stop and electrical power generation by the alternator/generator to cease.
The 'Battery Isolation' function is implemented by disconnecting the negative side of the vehicle’s battery from chassis/ground, thereby disconnecting the battery from ALL of the car's electrical systems.
When activated, the Engine Stop function occurs a very short period of time before Battery Isolation. Alternator load dump protection is also built in so no additional components are needed.
User operation
All CARTEK Battery Isolators are operated using two switches: A dashboard mounted 'Internal Switch' allows the driver to turn the Battery Isolator ON and OFF. An 'External Switch' is for operation by safety personnel in an emergency situation. The Internal Switch can be used to turn the Battery Isolator ON and OFF, however the External Switch can only turn the Battery Isolator OFF. This is in accordance with Motorsport UK safety regulations.
All CARTEK Battery Isolators also shut down automatically if a fault is detected such as short-circuit, over-current, over-temperature or broken cable connections. If this happens then the LED on the Battery Isolator unit, and the CARTEK Internal Switch, will display a flash pattern to indicate the cause of the fault.
