摘要：
本发明公开了一种控制中心，其在箱体(2)内所划分的、具有开关门(4)的单元室(3)中放置有可拉出的控制单元(5)，该控制单元(5)包括用于负载的开关、保护的主电路设备和保护控制继电器(8)，其中，保护控制继电器(8)配置在控制单元(5)内的前表面侧，并且容纳于从外部可开关的、由背面壳体(10)和前表面壳体(11)所形成的壳体内，保护控制继电器(8)的构成零部件中寿命短的电子零部件即显示基板(16)可装卸地安装在壳体内的底座基板(13)的前表面侧。
摘要（英）：

In a control center, a control unit (5) comprising a main circuit device for switching a load and a protection control relay (8) for protecting the load is housed in a drawable manner in a unit chamber (3) which is defined in a box (2) and which has an opening and closing door (4). In the control center, the protection control relay (8) is housed in a case which is arranged on the front surface side in the control unit (5), which is constituted in such a manner that the case can be opened and closed from the outside, and which comprises a rear surface case (10) and a front surface case (11). A display substrate (16) which is an electronic component having a short life out of components constituting the protection control relay (8) is detachably mounted on the front surface side of a base substrate (13) in the case.
