Motor Terminal Block ST 4-PE/3L
Three phases plus PE in one terminal block
With ST 4-PE/3L, Phoenix Contact can now also offer a four-level spring-cage terminal block for conductor cross sections of up to 4 mm2. As in the 2.5 mm2 version, it is also possible to wire three phases and the PE in one terminal block. The PE contact to the DIN rail is established by simply snapping it on. The ST 4-PE/3L is therefore particularly suited for space-saving wiring of three-phase motors. The nominal conductor cross section of 4 mm2 can also be connected without problems even when ferrules are used. With 28 amps per conductor, a nominal voltage of 800 V, and a width of a mere 6.2 mm, this terminal block is ideal for applications in the Þeld of drive and conveyor engineering. The ST 4-PE/3L can also be labeled and tested at every terminal point. The easy-to-read labeling in the terminal center makes it much simpler to clearly determine which load circuit it belongs to.
