Why run heavy battery cables all the way from your battery to your kill switch and back? The Cartek XR Battery Isolator is a compact, solid-state electrical master switch that can be mounted close to the battery. It is triggered by a push button switch which can be remote-mounted in the location specified by the rules.
Cartek isolators are designed to meet FIA and MSA requirements for electrical master kill switches. When a push button switch is pressed, the XR Isolator cuts off the ground connection to the battery and sends a shut-down signal to your ECU or ignition relay to positively turn the engine off.* Solid state construction means no moving parts and no potential for sparks when the switch is operated.
The isolator can be triggered by any number of normally closed, momentary-break switches (push button or toggle), connected in series using standard hookup wire (as small as 18 gauge). Just turn the switch off to kill the system. A latching (on-off) switch or your car's ignition switch can be used to reset the isolator. This Isolator does not include any trigger switches. The External Pushbutton Battery Isolator Switches are sold separately (Part No. 1068-110-Color).
We also stock the full Cartek XR Battery Isolator Kit with Blue External Button (Part No. 1068-119).
The XR Isolator can be used with 7 to 18 volt electrical systems (negative ground only). The battery switching circuit can handle a constant 450 amp battery load (2000A surge capacity). Draws just 25 mA when on and 0.1 mA when off. Maximum operating temperature 185° F. Measures 2 3/8" x 1 3/4" x 1 1/2" tall and weighs just 2 1/2 ounces. Perfect for formula cars! Designed and manufactured in the UK for professional racing.
Cartek Battery Isolator XR Instructions
*Note: The XR disconnects the battery ground connection 0.5 second after the ECU shut-down signal. This allows the ECU enough time to power down properly.
