摘要： PROBLEM TO BE SOLVED: To provide a plug-in distribution board that makes it possible to reduce its size when a large number of circuits are required. SOLUTION: A bus unit is so constructed that multiple vertical trunk bars 2 are disposed between a pair of mounting rails 3. The trunk bars 2 are disposed in parallel between the mounting rails 3 with both sides of them in the direction of which facing in the direction of the front and rear of the bus unit. Thus, a mounting space for electrical apparatuses is formed on both the front and rear sides of the bus unit. As a result, an electrical apparatus provided on its rear face with a plug-in terminal can be mounted from both the front and rear sides of the bus unit. The mounting rails 3 are so constructed that one side of each of them, wider than the trunk bars 2, is formed as one piece. A mounting face 3a for electrical apparatuses is formed on both sides of them. Thus, a number of required mounting rails 3 is reduced. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a circuit breaker for wiring in which a tripping action is carried out with a superior reactivity when electromagnetic repulsion occurs, and welding of a contact is prevented without causing an increase in the number of parts and reduction in assembling workability.
SOLUTION: An engaging part 30 for electromagnetic repulsion tripping is formed at a movable contact 9 of the circuit breaker for the wiring, and when the movable contact 9 floating-rises up by the electromagnetic repulsion, the tripping action is made to be carried out by directly acting on a trigger lever 14 of an open-close mechanism part 6. By this, opening electrode becomes possible with the superior reactivity, and the welding of the contact can be prevented. This breaker is especially suitable for the circuit breaker for the wiring wherein the movable contact 9 is installed in which a rotating shaft is installed upward of a movable contact point 11, and the lower part is made to be rotatable.

摘要： PROBLEM TO BE SOLVED: To provide a terminal block which makes it possible to connect a conventional-type breaker without a plug terminal, to the main electric line of a plug-in type distribution board easily. SOLUTION: Plug terminals 2 are provided at the tip of the body 10 of a terminal block. Be sides, electric wire connecting terminals 14 for leading load- side electric wires 15 out from the side of the body 10 are provided on the body. It does not matter if the electric wire connecting terminals 14 are screwless ones. These plug terminals 2 are inserted into the main electric line 3 of the plug-in type distribution board, and the load-side electric wires 15 are connected to a conventional-type breaker 4. Consequently, it becomes easy to draw electric wires about, by drawing load-side electric wires 15 out laterally. Besides, workability of screw tightening, etc., is enhanced, since the load-side electric wires 15 do not cover the upper parts of the connecting terminals.

摘要： PROBLEM TO BE SOLVED: To provide a distribution board suitable for respectively supplying an AC power and a DC power to an AC load and a DC load. SOLUTION: The distribution board includes an AC branch circuit 1 connected to a commercial power source and a DC branch circuit 2 connectible to this AC branch circuit 1 via an AC/DC power converter 3a. Thus, since the DC power can be supplied directly to a device using the DC power, it is not necessary to install an AC adapter at each device. COPYRIGHT: (C)2005,JPO&NCIPI
