Abstract

An adapter for contacting a circuit breaker to a busbar system, with a casing having a first mounting side to attach and electrically contact the adapter to at least one busbar of a busbar system and a second mounting side to attach and electrically contact a circuit breaker to the casing, characterized in that, on the second mounting side, at least one rotary disk with several sets of threaded inserts for attaching a circuit breaker is fitted so that it can pivot around a rotational axis perpendicular to the mounting sides, wherein each set of threaded inserts is equipped for mounting a particular type of circuit breaker so that for each position of the rotary disk one of the sets of threaded inserts is positioned in a mounting position for a particular type of circuit breaker.

First claim

The invention claimed is:

1. An adapter for connecting any one of a plurality of circuit breakers of different types to a busbar system, the adaptor comprising:
a casing having a first mounting side to attach and electrically connect the adapter to at least one busbar of the busbar system, and a second mounting side to attach and electrically connect any one of the plurality of circuit breakers of different types to the casing; and
on the second mounting side is at least one rotary disk with several sets of threaded inserts, the rotary disk and threaded inserts thereof pivot around a rotational axis perpendicular to the mounting sides;
wherein each one of the several sets of threaded inserts is equipped for mounting the adaptor to a different one of the plurality of circuit breakers of different types, for each rotational position of the rotary disk one of the plurality of sets of threaded inserts is positioned in a mounting position for one of the plurality of circuit breakers of different types;
wherein the rotary disk is incorporated in the casing, wherein the rotary disk has inscriptions identifying the several sets of threaded inserts;
wherein the second mounting side has a viewing window through which exactly one of the inscriptions can be seen according to the position of the rotary disk; and
wherein the sets of threaded inserts, the inscriptions and the viewing window are positioned so that the inscription indicating a particular set of the several sets of threaded inserts is visible through the viewing window when the particular set of the several sets of threaded inserts is positioned in the mounting position.

2. The adapter according to claim 1 , wherein the at least one rotary disk includes a first rotary disk and a second rotary disk that are positioned staggered on the second mounting side;
wherein the several sets of threaded inserts are first several sets of threaded inserts included with the first rotary disk;
wherein the second rotary disk includes second several sets of threaded inserts each equipped for mounting the adaptor to a different one of the plurality of circuit breakers of different types;
wherein the first rotary disk provides at least a first fastening point for any one of the plurality of circuit breakers of different types formed by the first set of threaded inserts, and the second rotary disk provides at least a second fastening point formed by the second set of threaded inserts and positioned staggered to the first fastening point.

3. The adapter according to claim 1 , wherein the rotary disk is incorporated in the casing, wherein the casing, in particular on the second mounting side, has a grip aperture to manually turn the rotary disk on the periphery of the rotary disk.

4. The adapter according to claim 1 , wherein
the second mounting side has at least one opening through which only the particular set of the several sets of threaded inserts in the mounting position is visible, and all other ones of the several sets of threaded inserts are not visible.

5. The adapter according to claim 1 ,
wherein the rotary disk is seated within a recess inside of the casing;
wherein the rotary disk has a substantially circular exterior circumference having latches;
wherein a latch site is located on the substantially circular inner circumference of the recess in the inside of the casing, and the latch site corresponds to the latches to receive any one of the latches therein; and
wherein the sets of threaded inserts, the latches and the latch site are positioned so that the rotary disk is in a corresponding lock-in position when one of the sets of threaded inserts is in the mounting position.

6. The adapter according to claim 1 , wherein the second mounting side is formed as an optionally removable cover for the inside of the casing in which the at least one rotary disk is incorporated, wherein the at least one rotary disk is interchangeably fixed to a turning shaft in the inside of the casing and is particularly clipped.

7. The adapter according to claim 1 , further having an adapter plate formed as a separate component having the at least one rotary disk, wherein the adapter plate is attached to the casing with the at least one rotary disk.

8. The adapter according to claim 7 , wherein the adapter plate is attached to an adapter plate insert of the casing with a releasable connection, the releasable connection including a screw or latch connection.

9. The adapter according to claim 7 , wherein the adapter plate is pre-mounted to any one of the plurality of circuit breakers of different types so that the circuit breaker to which the plate is pre-mounted and the adapter plate can be attached to the casing by inserting the adapter plate into the adaptor plate insert.
