Abstract
A circuit breaker for interrupting a direct current, in particular in a power supply system in a vehicle having a main current path that includes a switch, and having a reed relay for detecting an electric current flow across the main current path. The switch is coupled to the reed relay. Also, a use of a circuit breaker is provided.
Claims5
A circuit breaker for interrupting a direct current in an electrical system, comprising:
- a main current path that includes a switch;
- and
- a reed relay for detecting an electric current flow across the main current path,
- wherein the switch is coupled to the reed relay,
- wherein the switch has an armature which is disposed within an electric coil and is coupled to an auxiliary drive which has an eddy current drive,
- wherein the auxiliary drive is connected to the armature via a flexible connecting element,
- wherein the auxiliary drive has a first mechanical spring element.
The circuit breaker according to 2, wherein the eddy current drive includes a second mechanical spring element, a holding element and an actuating element positioned between the holding element and the second mechanical spring element, wherein the end member of the first mechanical spring element is latched to the holding element.
A circuit breaker for interrupting a direct current in an electrical system, comprising:
- a main current path that includes a switch;
- and
- a reed relay for detecting an electric current flow across the main current path,
- wherein the switch is coupled to the reed relay,
- wherein the main current path has a busbar which is peripherally surrounded in a positive manner by a carrier having a recess within which the reed relay is positioned,
- wherein the carrier is made of a ferromagnetic material, and
- wherein the recess forms a gap such that the carrier has two ends spaced apart from one another due to the gap.
