Aspects of the disclosure relate to a mechanical fuse (120). The mechanical fuse may include a top portion (200) having a first shear pin (270) configured to break when a predetermined side load is applied to the mechanical fuse. The mechanical fuse may also include a bottom portion (300) having a second shear pin (360), wherein the second shear pin is configured to break when a predetermined vertical load is applied to the mechanical fuse. Wherein the mechanical fuse may be arranged such that when the second shear pin is broken under the predetermined vertical load, the first shear pin also breaks before the bottom portion separates from the top portion, and when the first shear pin is broken under the predetermined side load, the second shear pin remains intact when the bottom portion separates from the top portion.
