    Cartek XR battery isolator unit only. This is now the and lightest isolator unit Cartek have ever produced. It's been designed specifically to connect to motorsport ECU's and Power Distribution Modules (PCM's). These units are built using solid state technology, so the XR battery cut off system is not effected by shock or vibration and has no moving parts. The units are also totally sealed against water and dirt, making them ideal for use in all forms of motorsport. The unit is so compact that it can be mounted very close to the battery, thus reducing the lengths of heavy battery cable required.

    Cockpit operation is performed via a single on/off push button switch and external operation is via one or multiple 'push' buttons to activate the unit and isolate the vehicle's electrics. Supplied here as the Cartek XR isolator unit only.

  • FAQs

    Is the Isolator FIA Approved?
    Unlike race seats, harnesses and fire extinguishers the FIA does not have an approval procedure for Master Switches. However, most FIA race and rally championships require cars to be fitted with a spark-proof master switch to isolate the battery from all electrical systems and stop the engine. The Cartek Battery Isolator meets these requirements.

    FIA ARTICLE 13 : GENERAL CIRCUIT BREAKER
    The general circuit breaker must cut all electrical circuits, battery, alternator or dynamo, lights, hooters, ignition, electrical controls, etc. and must also stop the engine.

    MSA: EXTERNAL CIRCUIT BREAKER
    8.1. The circuit breaker, when operated, must isolate all electrical circuits with the exception of those that operate fire extinguishers.

    How Does It work?
    The Solid State Isolator contains two isolation circuits. The first breaks the connection between the negative side of the vehicle’s battery from chassis/earth, thereby isolating the battery power from all electrical circuits, while the second cuts power to the engine electrics and thereby stops the engine from running.

    Why Solid State?
    Solid State means no moving parts, all power switching is fully electronic. Early types of electrical isolation were by large mechanical master-switches while more modern systems have utilised electro-mechanical solenoids. Both of these types of systems contain mechanical electrical contacts which, due to the combination of high electrical current and the shocks and vibration of the race car environment, sparking between the contacts occurs which results in contact erosion and eventual unreliability. This Solid State Isolator is also filled with a hard setting resin which prevents any ingress of dust, dirt or water therefore further increasing its strength and reliability.

    How Is It Controlled?
    The two electronic isolation circuits are controlled by microprocessors and incorporate various safety systems including over-temperature and over-current monitoring. These microprocessors also monitor the kill switches/buttons for instant activation without false triggering. The unit will instantly trigger into isolation mode when any of the kill buttons are struck or on detection of any fault or break in switch wiring circuits.

    How Is It Operated?
    The Isolator can be controlled by any number of switches although the usual configuration is one internal on-off switch and one external kill button. All switches/push-buttons are connected to the Isolator via light weight, low current wiring.
    If required, multiple kill switches/devices can be incorporated, alternatively the system can be configured to be operated by a single on-off switch/push button. The Isolator will also automatically trip into isolation mode if any wire connection becomes broken due to fatigue or accident.
