FIELD: electrical engineering.
SUBSTANCE: invention can be applied to electrical engineering. Disclosed is device (1) for protection of power compartments, which receives input signal (3) of fuse based on state of fuse (4) for device (5) for controlling power compartments and input signal (6) of reduced current, associated with low current for one of lines (7) of power supply of compartment (8), processes input signal (3) of fuse based on state of fuse and input signal (6) of reduced current and detects torn wire (9) in other power module (8).
EFFECT: technical result is providing control of power compartment in absence of state of failure.
