Abstract
A circuit breaker having a mechanical switch introduced into a main current path, which comprises a fixed contact and a moving contact connected to a movably mounted contact bridge. The circuit breaker comprises a drive, which is in active connection with the contact bridge, and which comprises a first drive unit and a second drive unit. The first drive unit is energized via a control circuit, and the second drive unit is connected in parallel to a resistor element introduced into the main current path. The invention also relates to a motor vehicle.
Claims9
A circuit breaker comprising:
- a mechanical switch provided in a main current path, the mechanical switch having a fixed contact and a moving contact, the moving contact being connected to a movably mounted contact bridge;
- and
- a drive, which is in active connection with the contact bridge, the drive having a first drive unit and a second drive unit,
- wherein the first drive unit is energized via a control circuit,
- wherein the second drive unit is connected in parallel to a resistor element provided in the main current path, and
- wherein between the second drive unit and the main current path, a Zener diode and/or a second switch is connected.
A circuit breaker comprising:
- a mechanical switch provided in a main current path, the mechanical switch having a fixed contact and a moving contact, the moving contact being connected to a movably mounted contact bridge;
- and
