Abstract: The present disclosure relates to a hydraulic fuse comprising: a fuse body defining a plenum, the plenum comprising: an inlet configured to couple to a first fluid location; and an outlet configured to couple to a second fluid location. The hydraulic fuse further comprises a first fuse element arranged to close the inlet, the first fuse element configured to open the inlet when a pressure differential between the first fluid location and the plenum reaches a first threshold; and a second fuse element arranged to close the outlet, the second fuse element configured to open the outlet when a pressure differential between the plenum and the second fluid location reaches a second threshold, wherein the first threshold is higher than the second threshold
