Abstract: A combination electric motor control and pump protective assembly in which a protective unit is readily inserted as a module into an existing motor control unit. The units which form the single combined assembly are electrically attached together by blade and socket members to which electrical devices are connected. Thus, a pump protective unit can be quickly and readily added to an existing motor control unit which is mounted upon support structure. Therefore, a motor control unit and a pump protective unit is quickly formed into a combined assembly upon existing support structure, without the mounting of an additional member upon support structure and without additional wiring.
