FIELD: electrical engineering.

SUBSTANCE: invention relates to electric power distribution centers and motor control centers, in particular to pull-out units, which can be completely removed from the assembly of low-voltage distribution equipment and control equipment without switching off the assembly. For this purpose, the pull-out unit for the compartment of the functional unit of the unit of low-voltage distribution equipment or control equipment has a locking mechanism controlled by a push button in the test and connected positions, isolated lockable mechanism for maintenance and release mechanism to prevent falling of pull-out unit from compartment of functional unit of specified unit. To prevent accidental insertion of the pull-out unit into an improper compartment of the functional unit, an insertion lock is provided. Pull-out unit contains gaskets, which improves the degree of protection (IP code) when the pull-out unit is in a fully connected position.
