1. A fluid cooling device for a circuit breaker, the device having an annular main body comprising:
a front surface;
a back surface;
an outer portion comprising outer and inner surfaces;
a central passage connecting an aperture of the front surface to an aperture of the back surface, the central passage being adapted to receive a rod of the circuit breaker; and
a plurality of side passages through the outer portion connecting the front surface to the back surface, the plurality of side passages comprising an inner passage surface allowing flow of the fluid through the outer portion of the annular main body, the plurality of side passages having a heat transfer rate being higher than a heat transfer rate of the central passage.
