ENERGY HARVESTING MODULE

A system includes: a current interrupting module including: a first housing and a switching device in the first housing, the switching device configured to control an electrical connection between a first node of an electrical system and a second node of an electrical system in response to a control signal; and an energy harvesting module including: a control apparatus configured to output the control signal; an energy harvesting apparatus electrically connected to the control apparatus; and a second housing that at least partially encloses the energy harvesting apparatus and the control apparatus. The energy harvesting apparatus is electrically connected to the first node regardless of a state of the switching device.
