CARTEK XR electronic battery isolator (blue switch) CK-BR-08-B

Discover the CARTEK XR electronic battery isolator with its blue switch, designed to meet FIA requirements by performing two essential functions: stopping the engine and disconnecting the battery from all electrical systems. This device cuts power to the ECU or ignition circuit, stopping the engine and power generation by the alternator/generator. It then isolates the battery by disconnecting its negative terminal from the chassis/earth, protecting all the vehicle’s electrical systems. Its load-dump protection means no additional components are required. Operating between 7V and 18V, it consumes 7mA in OFF mode and 50mA in ON mode.

XR model technical specifications:

• Dimensions: 60 x 45 mm
• Weight: 70g
• Breaking capacity: 550 650A / 2000A peak
• Engine shutdown signal current: ECU / PDM signal
• Connectors: Sealed wires
• Switch colour: Blue
• Supplied as a complete kit: battery isolator, internal switch, external switch and battery isolator sticker.

CARTEK battery isolators are fully electronic, with no moving parts, and hermetically sealed for maximum protection against water and dust. They resist shocks and vibrations, incorporate an alternator de-excitation circuit and allow direct control using a single ON-OFF switch or external buttons. Their thin, lightweight wiring (70g to 120g) simplifies installation, while positioning close to the battery reduces connection lengths. Complying with FIA standards, they are designed and manufactured in the United Kingdom using high-quality, latest-generation components.

Four models are available:

• GT model: Suitable for most racing and rally cars. Includes 600A battery isolation and a fully protected 30A power output for the ECU, ignition or fuel system.
• XR model: More compact and lighter than the GT, designed specifically to connect to ECU modules (PDM or PCM). Supplied with a sealed connection wire.
• X-Pro model: Designed to handle the high starting currents of large-displacement, high-power racing engines. Configurable engine shutdown output (5A 20A selectable) with signal connections via a sealed DT Deutsch connector.
• X-Club model: Ideal for medium-power cars and engines up to 3.0L V6, turbocharged or naturally aspirated. Perfect for one-make championships with standard engines, such as Audi TT, Civic Type R, MX5, Clio, Mini, etc. Fully protected 10A power output for ignition coils, engine relays or ECU/PDM input.
