    Abstract: A cooling device for use with circuit interrupters includes a housing structured to be coupled to a terminal of the circuit interrupter and formed with several ventilation openings, as well as a permanent magnet, a torque converter and a fan blade all contained within the housing. When the cooling device is coupled to a terminal of a circuit interrupter and current flows through the terminals of the circuit interrupter, parasitic magnetic fields are generated and induce oscillatory motion of the permanent magnet. The torque converter is coupled to the permanent magnet and converts the oscillatory motion of the magnet to rotational motion that rotates the fan blade. The fan blade is disposed near the ventilation openings of the housing so that air flow produced by rotation of the fan blade travels across the surface of the circuit interrupter terminal nearest the ventilation openings to increase convection.

    Abstract: A current interruption module includes: a resettable switching apparatus associated with operating states, the operating states including at least a first operating state that prevents current flow in the switching apparatus and a second operating state that allows current flow in the switching apparatus; a switch control configured to control the operating state of the switching apparatus; an electrical interface configured to electrically connect the switching apparatus to a load; and a connection interface configured to electrically connect the resettable switching apparatus to a current path of an separate and distinct electrical connector and to mechanically connect the current interruption module to the separate and distinct electrical connector.
