Claims

[Scope of Claim for Utility Model Registration] A collective starter panel in which unit bodies each equipped with a control device are housed in multiple tiers,
In the electrical connection between a molded circuit breaker mounted on the unit unit body and a busbar provided in a rear space of a rear plate of the unit unit body, a plug-in connection that is inserted into and removed from the busbar. A leg portion for accommodating the terminal and a part of the stud-type terminal conductor integrally connected to the plug-in connection terminal, and a flange-shaped portion provided around the leg portion are integrally formed with a molded insulator. a plug-in terminal block, which is formed in a manner that the legs protrude from an opening formed in a back plate of the unit body to the rear surface side; and a stud-type terminal conductor of the plug-in terminal block. A terminal conductor is provided with a terminal shelf and a molded insulator in which a through hole is formed to accommodate a portion of the terminal conductor, and one end of the terminal conductor on the power supply side led out to the terminal shelf and the stud-type terminal conductor are integrally connected by a terminal screw. and a molded circuit breaker integrally attached to the front surface of the plug-in terminal block, and when the unit body is stored in or extracted from the board, the bus bar and the plug-in connection terminal are connected and disconnected, respectively. A collective activation board that is characterized by:
