1. A poly-phase current control device, comprising:

  • a first current path;

    a first set of conduction interfaces comprising a first interface disposed at one end of the first current path and a second interface disposed at an opposite end of the first current path, wherein the first interface and the second interface are configured to couple with a fuse terminal;

    a first micro electromechanical system (MEMS) switch disposed between the first interface and the second interface;

    a second current path;

    a second set of conduction disposed proximate the first set of conduction interfaces, the second set of conduction interfaces comprising a third interface disposed at one end of the second current path and a fourth interface disposed at an opposite end of the second current path, wherein the third interface and the fourth interface are configured to couple with the fuse terminal;

    a second micro electromechanical system (MEMS) switch disposed between the third interface and the fourth interface;

    control circuitry in signal communication with the first current path and second current path, wherein the control circuitry configured to facilitate an interruption in response to an electrical current passing through any one of the first current path and second current path meeting a parameter of a defined trip event, via the first MEMS switch and second MEMS switche;

    an activator in signal communication with the control circuitry and configured to close the first MEMS switch and second MEMS switch in response to a signal subsequent to the defined trip event;

    an indicator in signal communication with the control circuitry to indicate an occurrence of the defined trip event; and

    an input device in signal communication with the control circuitry and configured to transmit to the control circuitry the parameter of the defined trip event.
