An electrical apparatus, including: a circuit breaker having a breaking capacity and a breaking current; a DC voltage source including two batteries connected in parallel, connected in series with the circuit breaker, the sum of short-circuit currents of the batteries being greater than the breaking capacity, each battery including: a first branch including storage batteries and a switch connected in series; a second branch connected in parallel with the first branch and including a free-wheeling diode; an ammeter measuring output current; and a control circuit configured to detect a short-circuit. The control circuits simultaneously keep a majority of switches open and close one switch to apply a current passing through the circuit breaker which is higher than the breaking current and lower than the breaking capacity.
