Arrangement for protecting an electrical device
First Claim
1. An arrangement for protection of an electrical device having a pole terminal (4) which is connected to one pole (3) of a battery (1) and to which the electrical device is connected, having a protective contact unit (9) which has a connecting section (10) (which is electrically connected directly to the pole terminal (4)) and a starting assistance contact section (11), with the connecting section (10) and the starting assistance contact section (11) being electrically connected in series by means of an intermediate closed switch (12), and having an evaluation circuit (15) which opens the switch (12) as soon as it detects a fault current, with a main line (5) being provided, which is electrically connected to the starting assistance contact section (11) as a function of the switch position of the switch (12) and leads to at least one second electrical device, and the first device being electrically connected to the pole terminal (4), bypassing the main line (5) and independently of the switch position of the switch (12).

Abstract
The present invention relates to an arrangement (7) for protection of an electrical device. In this case, the device is connected via one pole terminal (4) to one pole (3) of a battery (1) . A protective contact unit (9) has a connecting section (10) which is connected directly to the pole terminal (4), and has a starting assistance contact section (11) which is connected to the connecting section (10) via a switch (12). An evaluation circuit (15) operates the switch (12) in order to disconnect the electrical connection between the starting assistance contact section (11) and the connecting section (10) as soon as the evaluation circuit (15) detects a fault current.
