FIELD: electric engineering.
SUBSTANCE: invention is related to compact device of protective disconnection with expanded functionality, which has casing, in which commutation device is installed, as well as short-circuit current unlocking and device of damage current unlocking. In order to increase device compactness and in particular for realisation of its narrow structural version, centers of commutation device, device of short-circuit current unlocking and device of damage current unlocking are mainly locate in one plane, and commutation device is installed between device of short-circuit current unlocking and device of damage current unlocking. By means of that, for example, it is possible to combine linear protective breaker with switches of damage currents protection in single module, the width of which is multiple to 18 mm.
EFFECT: increase of device compactness.
