Abstract

An improved circuit breaker is disclosed herein. The improved circuit breaker includes one or more main contacts and only one resistor contact. The only one resistor contact is connected in parallel with at least one of the one or more main contacts.

Claims (11)

1. A circuit breaker comprising:

a plurality of main contacts, wherein each main contact of the plurality of main contacts comprises a fixed terminal and a moving terminal;

one and only one resistor contact having a fixed terminal and a moving terminal, wherein the one and only one resistor contact is connected in parallel with at least one main contact of the plurality of main contacts; and

at least one breaker tank comprising a plurality of mechanical links, wherein the plurality of mechanical links is connected with the moving terminal of each main contact of the plurality of main contacts and the moving terminal of the one and only one resistor contact,

wherein the at least one breaker tank is configured to perform one or more of closing and opening of the plurality of main contacts and the one and only one resistor contact, and

wherein, in a closed configuration of the circuit breaker, the moving terminals of two main contacts of the plurality of main contacts are connected with the respective fixed terminals of the two main contacts and the moving terminal of the one and only resistor contact is not connected with the fixed terminal of the one and only resistor contact.

2. The circuit breaker of claim 1 , wherein the one and only one resistor contact comprises at least one resistive component.

3. The circuit breaker of claim 2 , wherein the plurality of main contacts are enclosed in one or more interrupter units.

4. The circuit breaker of claim 2 , wherein the one and only one resistor contact is enclosed in one and only one closing resistor unit.

5. The circuit breaker of claim 1 , wherein the plurality of main contacts are enclosed in one or more interrupter units.

6. The circuit breaker of claim 1 , wherein the one and only one resistor contact is enclosed in one and only one closing resistor unit.
