The 12v Sealey Auto Electronics Protection Device (Model PROSAF/12) is specifically designed for standard passenger vehicles and light commercial applications operating on 12-volt electrical systems. This essential workshop safety device clips across battery terminals to prevent damaging voltage spikes from reaching sensitive vehicle electronics during maintenance procedures. Ideal for protecting modern 12v vehicles during welding, plasma cutting and jump starting operations, this unit safeguards expensive components including coded radios, alarms, ECUs and fuel tank senders. The tough composite housing protects the internal circuitry whilst heavy-duty, fully insulated battery clips ensure secure, safe connection. A convenient LED indicator system displays operational status with a green light confirming correct operation and a red warning light for any faults, providing instant visual confirmation that your vehicle's electronics are protected.
