ABSTRACT:
At least one embodiment of the invention provides that, for a closing apparatus for a part rack withdrawable via V-shaped rod assemblies, the closing apparatus includes at least one pin formed on rod assemblies or as part of them, each pin engaging in a slot in an actuating element. Owing to the use of the slots, the actuating element can be formed as a rigid body, with the result that no frictional forces need to be overcome when inserting a circuit breaker into a withdrawable-part rack with the closing apparatus according to at least one embodiment of the invention. With the closing apparatus according to at least one embodiment of the invention, a locking element can have a particularly simple design: it can be guided in the actuating element.
