Abstract

A circuit breaker baying a switch housing and at least one contact for tapping a voltage on a primary conductor.

First claim

The invention claimed is:

1. A circuit breaker, comprising:
a circuit-breaker housing including a side wall through which a primary conductor with a high voltage is fed into the circuit-breaker housing;
a switch electronics unit; and
an adapter assembly housing arranged in the side wall of the circuit-breaker housing, the adapter assembly housing accommodating at least one adapter, the adapter comprising:
a printed circuit board;
a spring element in contact with the primary conductor, the spring element being joined to the printed circuit board; and
a voltage divider that reduces a tapped high voltage from the primary conductor to a low voltage for use in the switch electronics unit, the voltage divider being arranged on the printed circuit board and between the spring element and a low-voltage contact that transmits the low voltage to the switch electronics unit,

wherein the spring element includes a plurality of leaf springs,
wherein the plurality of leaf springs are arranged in a receiving opening for the primary conductor.

2. The circuit breaker of claim 1 , wherein the voltage divider is connected to the spring element via a conductor track.

3. A circuit breaker, comprising:
a circuit-breaker housing including a side wall through which a primary conductor with a high voltage is fed into the circuit-breaker housing;
a switch electronics unit; and
an adapter assembly housing arranged in the side wall of the circuit-breaker housing, the adapter assembly housing accommodating at least one adapter, the adapter comprising:
a printed circuit board;
a spring element in contact with the primary conductor, the spring element being joined to the printed circuit board; and
a voltage divider that reduces a tapped high voltage from the primary conductor to a low voltage for use in the switch electronics unit, the voltage divider being arranged on the printed circuit board and between the spring element and a low-voltage contact that transmits the low voltage to the switch electronics unit,

wherein the spring element includes a coil spring,
wherein the coil spring arranged in a receiving opening for the primary conductor.

4. A circuit breaker, comprising:
a circuit-breaker housing including a side wall through which a primary conductor with a high voltage is fed into the circuit-breaker housing;
a switch electronics unit; and
an adapter assembly housing arranged in the side wall of the circuit-breaker housing, the adapter assembly housing accommodating at least one adapter, the adapter comprising:
a printed circuit board;
a spring element in contact with the primary conductor, the spring element being joined to the printed circuit board; and
a voltage divider that reduces a tapped high voltage from the primary conductor to a low voltage for use in the switch electronics unit, the voltage divider being arranged on the printed circuit board and between the spring element and a low-voltage contact that transmits the low voltage to the switch electronics unit,

wherein the spring element includes a leaf spring,
wherein the leaf spring is arranged in a receiving opening for the primary conductor.

5. A circuit breaker, comprising:
a circuit-breaker housing including a side wall through which a primary conductor with a high voltage is fed into the circuit-breaker housing;
a switch electronics unit; and
an adapter assembly housing arranged in the side wall of the circuit-breaker housing, the adapter assembly housing accommodating at least one adapter, the adapter comprising:
a printed circuit board;
a spring element in contact with the primary conductor, the spring element being joined to the printed circuit board; and
a voltage divider that reduces a tapped high voltage from the primary conductor to a low voltage for use in the switch electronics unit, the voltage divider being arranged on the printed circuit board and between the spring element and a low-voltage contact that transmits the low voltage to the switch electronics unit,

wherein the spring element includes a spring-loadable telescopic arrangement,
wherein the spring-loadable telescopic arrangement is arranged in a receiving opening for the primary conductor.

6. The circuit breaker of claim 1 , wherein the receiving opening for the primary conductor is arranged in a converter block.

7. The circuit breaker of claim 1 , wherein the circuit breaker is configured such that a contact between the leaf springs of the spring element and the primary conductor can be made when the primary conductor is provided.

8. The circuit breaker of claim 1 , configured as a multi-pole circuit breaker,
wherein a plurality of primary conductors are assigned a corresponding number of contacts for tapping the voltage.

9. The circuit breaker of claim 8 , comprising a plurality of printed circuit boards arranged in the adapter assembly housing, wherein the printed circuit board is one of the plurality of printed circuit boards.
