PROBLEM TO BE SOLVED: To provide a protection/control device of electric apparatus which is easily and surely installed at low cost, mechanically and electrically connects a plurality of electric devices in series with ease, and performs a logic function with ease, and also to provide an electric device usable for a protection/control system. SOLUTION: The protection/control system, composed of a plurality of multi-pole switches having cases (10, 20, 30) is constructed so that upstream/downstream connection conductor bars protruding from upstream/downstream horizontal connection areas of the respective cases (10, 20, 30) along a vertical axis, are inserted into opening parts (44) of detachment-free power terminal stands (40, 40', 50, 50', 60). The system is provided with at least one connection element (80, 80') electrically connecting a first electric device of the protection/control system with a second electric device thereof. One connection element (80) is located between the case (10) of the first electric device and the power terminal stands (40, 50), and the other connection element (80') is located between the case (20) of the second electric device and the power terminal stands (40', 50').
