Title: ARRANGEMENT FOR PROTECTING ELECTRICAL LOADS AND THE CONNECTION LINES THEREOF FROM OVERCURRENT
Abstract:
A protective arrangement (20) for protecting electrical loads and the connection lines thereof from overcurrent is described. In this case, the protective arrangement has an input (E), at which an input current is supplied to the protective arrangement from a current supply (10), and at least one output (A), to which a connection line for supplying a load with current can be connected. A current supply path is arranged between the input (E) and the output (A). According to the invention, two path circuit breakers for interrupting the current flow are arranged in this case in a series circuit in the current supply path, wherein the protective arrangement (20) has a setting unit (20A) which can be used to set a trip current at least for one of the path circuit breakers, upon the exceeding of which the path circuit breaker interrupts the current flow.
