The ST 4-PE/3L is a Phoenix Contact four-level spring cage terminal block for conductor cross sections up to 4 mm2. Like 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.
The ST 4-PE/3L is a four‑level spring‑cage terminal block that allows three phases and a protective earth (PE) to be wired in a single compact unit. With a width of only 6.2 mm, it is suited for space‑saving installations in drive and conveyor engineering, and the PE contact snaps onto the DIN rail for easy mounting.
The handbook lists detailed technical data, including a nominal voltage of 800 V, a rated current of 28 A per conductor, and a maximum load current of 32 A for a 6 mm² cross‑section. Dimensions, stripping length, insulation material (PA, UL 94 V0), and various IEC/DIN test results are also provided.
