A trip cam is for an operating handle assembly of an electrical switching apparatus. The electrical switching apparatus includes a housing and a number of poles. The operating handle assembly has an operating handle partially extending into the housing. The trip cam includes a mounting portion structured to be disposed in the housing, and an operating handle protrusion extending from the mounting portion and being structured to engage the operating handle.

A non-electrical device (40) includes first and second half-housings which are produced in a plastic material, are joined fixedly to one another, define an axis along which a passage for an electrical conductor passes through the first and second half-housings, and delimit between them an internal volume, which is separated from the passage and which surrounds the passage all around the axis. The first half-housing incorporates, by moulding, mechanical reinforcing elements which extend substantially parallel to the axis in the internal volume until they are in contact with the second half-housing.

A trip cam is for an operating handle assembly of an electrical switching apparatus. The electrical switching apparatus includes a housing and a number of poles. The operating handle assembly includes an operating handle partially extending into the housing and a cradle member cooperating with the operating handle. The trip cam includes: a mounting portion structured to be disposed in the housing, the mounting portion including a first region, a second region disposed generally opposite the first region, and a third region disposed generally between the first region and the second region; a transfer leg extending from the first region and being structured to cooperate with each of the number of poles; a driving leg extending from the third region and being structured to be driven by the cradle member; and an operating handle protrusion extending from the second region and being structured to engage the operating handle.
