What does an isolation guard do?

Unlike fixed battery systems, mobile battery systems usually do not have a ground fault circuit interrupter.
An earth leakage circuit breaker protects against potentially deadly ground fault currents.
To prevent dangerous situations in mobile applications, such as a service truck, Intercel offers several insulation guards.
When inside the service car, one is protected from ground fault currents by the insulating effect of the service car’s rubber tires.
Outside the vehicle, however, there is a risk of ground fault currents.
As soon as a ground fault current threatens to occur, the insulation guard automatically switches off the 230 Volt system.
This ensures the safety of the user and eliminates the need to drive a separate earth pin into the ground.
In this way, safety and convenience go hand in hand.
