Claims6
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.
