The FIA 6-Pole Master Battery Isolator Switch is a mandatory safety device for all competition vehicles requiring compliance with FIA regulations. This heavy-duty master cut-off switch ensures a complete and immediate electrical shutdown of your vehicle in emergency situations, protecting both the driver and the vehicle's sensitive electronics.
Unlike simple 2-pole switches, this 6-pole design cuts power to the entire system, stops the engine instantly, and safeguards your alternator from damage.
•   Complete System Isolation: Simultaneously cuts the main battery positive supply and isolates the entire electrical system.
•   Instant Engine Kill: Includes a dedicated circuit to interrupt the ignition, ECU, or fuel pump relay, guaranteeing the engine stops immediately upon activation.
•   Alternator Protection: Features a third circuit and a ceramic discharge resistor to safely dissipate residual voltage from the alternator, preventing damaging voltage spikes that can fry your ECU and electronics.
•   High Current Rating: Built to handle the rigorous demands of racing, with high momentary and continuous current capacities (ratings vary by specific model).
•   Universal Fitment: Suitable for use in both 12v and 24v electrical systems.
•   Safety Compliance: Meets the strict safety requirements of the FIA and most global motorsport sanctioning bodies.
