Phoenix Contact PT 16 N BU Push-in Terminal Block, Blue, 2-Position, 76 A, 1000 V, DIN Rail Mount

This Phoenix Contact PT 16 N BU is a push-in terminal block engineered for fast, tool-free wiring of solid and stranded conductors up to 16 mm². Its blue insulating body provides clear visual identification, while the push-in connection technology ensures secure, vibration-resistant terminations. Rated for 76 A and 1000 V, it is suitable for demanding industrial control and power distribution applications. The block mounts on standard DIN rails NS 35/7.5 or NS 35/15, and its compact design saves space in control cabinets.

Advantages

The push-in connection system allows direct insertion of solid conductors or stranded conductors with ferrules without tools, reducing installation time by up to 50% compared to screw connections. The blue color coding aids in circuit identification and error prevention. The PA insulating material is halogen-free and flame-retardant (UL 94 V0), ensuring safety in fire-sensitive environments. The terminal block withstands a wide temperature range from -60 °C to 105 °C, making it reliable in harsh conditions. Its high current rating of 76 A and voltage rating of 1000 V meet the requirements of most industrial power circuits.

Recommendations

For optimal performance, use ferrules on stranded conductors to ensure reliable push-in connections. Verify that the DIN rail is properly grounded and that the terminal block is securely snapped onto the rail. When wiring, strip the conductor to exactly 12 mm to achieve full insertion and contact. This terminal block is ideal for applications where frequent wiring changes or high vibration are expected, thanks to its maintenance-free spring connection.
