Knife disconnect terminal block ST 2,5-TWIN-MT/1P and disconnect terminal block ST 2,5-TWIN-TG/1P have two spring cage connection facilities on the one side of the disconnect zone, and on the other side, a connection facility for the SP 2,5 plug. There are test facilities for 2.3 mm[2] test plugs on both sides of the disconnect point. The external dimensions of the terminal blocks match the shape of the ST-COMBI series and it goes without saying that the same accessories are used (labeling, bridges, test plugs). As a particular feature, both terminal blocks have 3 bridge shafts: two in the same position as in the entire ST series and one on the other side of the disconnect point. Whereas in the case of the knife disconnect terminal block the knife is fitted, in the case of the disconnect terminal block, the P-DI disconnect plug can be mounted. If the disconnect point is to remain open, the disconnect plug can be "parked" the other way round in the terminal block. The P-CO component plug can also be used in the univeral disconnect zone of the above-mentioned series. To make wiring the component as convenient as possible, both spring-cage contact points are opened at the same time by twisting the screwdriver. Phoenix Contact GmbH & Co.
