Phoenix 3211757 PT 4 Ακροδέκτης διέλευσης, Push-in, 4 mm², 1000 V, 32 A, Γκρι

The Phoenix 3211757 PT 4 stands out as a compact single-level feed-through terminal block engineered for high-density wiring in control cabinets and distribution boxes. Unlike screw-clamp alternatives, its push-in connection technology allows solid conductors and ferruled stranded wires to be inserted directly without tools, cutting installation time by up to 50%. With a 4 mm² nominal cross-section and a 1000 V IEC rating, it handles demanding industrial loads while maintaining a slim 6.2 mm profile that maximizes rail space.

Highlights

• Push-in connection: tool-free insertion for solid and ferruled conductors from 0.2 to 6 mm²
• Rated for 1000 V / 32 A per IEC 60947-7-1, suitable for 3-phase systems up to 690 V AC
• Only 6.2 mm wide, enabling up to 161 terminals per meter on a DIN rail
• Durable polyamide housing in grey, halogen-free and self-extinguishing per UL 94 V0
• Wide operating temperature range from -60 °C to +105 °C for harsh environments

In daily use

Installation is straightforward: snap the terminal onto a standard NS 35/7.5 or NS 35/15 DIN rail, prepare conductors with a stripping length of 9–11 mm, and push them into the clearly marked entry funnels. The integrated test pick allows easy voltage testing without disconnecting wires. For stranded conductors without ferrules, simply press the orange pusher with a screwdriver to open the spring clamp. The terminal's symmetrical design permits left-to-right or right-to-left wiring, and the large marking surface accepts standard Zack strips for clear circuit identification.
