Phoenix 3212138 PT 16 N Feed-Through Terminal Block, Push-in Connection, 16 mm², 1000 V, 76 A, Grey

The PT 16 N stands out in the Phoenix Contact portfolio by combining a generous 16 mm² nominal cross-section with push-in connection technology, enabling tool-free wiring of conductors up to 16 AWG without sacrificing the reliability expected in industrial feed-through terminals. Unlike screw-clamp alternatives, this terminal block reduces installation time significantly while maintaining a vibration-resistant, gas-tight contact — a practical advantage in control cabinets and machine wiring where speed and long-term stability matter.

Highlights

• Push-in connection: solid conductors and ferruled stranded wires simply push in; no tools required for wiring.
• High current capacity: rated for 76 A at 1000 V IEC, suitable for power distribution and motor circuits.
• Wide conductor range: accepts 6–16 AWG (16 mm² nominal), flexible for various cable sizes.
• Compact grey housing: polyamide PA 66, UL 94 V0 flammability rating, halogen-free.
• Global approvals: UL, cUL, KEMA-KEUR, EAC, ATEX, IECEx — ready for international projects and hazardous areas.
• DIN rail mounting: fits standard NS 35/7.5 and NS 35/15 rails, no special tools needed.

In daily use

Installers appreciate the PT 16 N for its straightforward handling: strip 18 mm of insulation, insert the conductor, and the push-in spring clamps it securely. The terminal block provides two connection points on a single potential, making it ideal for feed-through applications in distribution boards, motor control centers, and automation panels. Its grey color blends with standard cabinet wiring, and the compact dimensions (approx. 12 mm width) allow high packing density on the rail. The operating temperature range from -60 °C to +105 °C ensures reliable performance even in harsh environments, while the 8 kV rated surge voltage and pollution degree 3 rating confirm its robustness in industrial settings.
