A modular terminal having a terminal housing, a busbar, and two terminal elements for connecting two conductors to the busbar. Two functional slots are formed at both connecting ends in the terminal housing. The first functional slot provides a first connection possibility for a first test socket or a test plug, and, the second functional slot provides a second connection possibility for a fixed link or a jumper. In order to be able to mount the testing and switching equipment in a simple and flexible manner in the modular terminal, an additional third functional slot is formed at both connecting ends in the terminal housing, a third connection possibility corresponding to the third functional slot is formed at both connecting ends in the busbar, and the connection possibilities in the busbar are openings into which test sockets, test plugs, fixed links, or jumpers can be alternatively plugged.
