Safety Circuit Breaker: Description and Operation
Battery Interrupt Igniter
General Information
-
The Battery Interrupt Igniter N253 is installed when the battery is installed in the vehicle interior or luggage compartment.
-
This design results in longer routing of the battery wire to the starter, which results in an increased risk of burning due to wiring damage in case of
an accident.
-
In the case of a crash with airbag deployment, the positive connection from the battery to the starter is pyrotechnically separated.
-
However, the electrical system voltage supply remains for important safety functions such as hazard lights and lighting.
-
The Battery Interrupt Igniter N253 is integrated in the main fuse box. It is located in the luggage compartment on the left starter battery.
