Abstract: A cooling apparatus is provided for a switchgear. The switchgear has one or more primary contacts constructed and arranged to connect to a terminal of a circuit breaker. The cooling apparatus includes an evaporator constructed and arranged to be associated with each primary contact. A condenser is located at a higher elevation than the evaporator. Fluid conduit structure fluidly connects the evaporator with the condenser. A portion of the fluid conduit structure defines a busbar tube electrically connected with an associated primary contact and defining a busbar of the switchgear. Working fluid is in the evaporator so as to be heated to a vapor state, with the fluid conduit structure being constructed and arranged to transfer the vapor to the condenser and to passively return condensed working fluid back to the evaporator for cooling the at least one primary contact and the associated busbar tube.
