Mobile application with combined breaker and relay

A breaker/relay, comprising:

• a plurality of fixed contacts electrically coupled to electric load circuits for a mobile application;
• a plurality of movable contacts, each movable contact selectively electrically coupled to a corresponding one of the plurality of fixed contacts;
• a plurality of armatures each operationally coupled to a corresponding one of the movable contacts, such that each armature in a first position prevents electrical coupling between the corresponding movable contact and the corresponding fixed contact, and each armature in a second position allows electrical coupling between the corresponding movable contact and the corresponding fixed contact;
• and
• a current response circuit structured to determine a current in each of the electric load circuits, and further structured to provide an armature command to open the corresponding one of the movable contacts in response to the current in that electrical load circuit indicating a high current value.

A method, comprising:

• determining a first current value in a first electric load circuit of electric load circuits for a mobile application;
• determining a second current value in a second electric load circuit of the electric load circuits for the mobile application;
• and
• in response to one of the first current value exceeding a first high current value or the second current value exceeding a second high current value, providing armature command to open a contactor of a plurality of armatures for a corresponding one of the first electric load circuit or the second electric load circuit.
