Phoenix Contact PTI 2,5-PE/L/N Installation Terminal Block, Push-in, 3-Level, 24 A, 400 V, Grey

Installation terminal block with push-in connection, three-level design (PE, L, N), and six connection points, engineered for reliable power distribution in building installations. The Phoenix Contact PTI 2,5-PE/L/N combines a compact footprint with high current capacity, simplifying wiring in distribution boards and control panels.

Advantages

Tool-free push-in termination accelerates installation and reduces wiring errors. The integrated PE level with green-yellow insulation ensures clear grounding identification, while the L and N levels maintain consistent phase and neutral separation. Rated for 24 A and 400 V, this block handles demanding residential and commercial circuits. Polyamide housing offers high mechanical strength and flame retardancy (UL 94 V0), and the wide operating temperature range (-60 °C to 105 °C) suits harsh environments.

Recommendations

For optimal performance, use ferrules on stranded conductors and ensure the DIN rail is properly grounded. Combine with Phoenix Contact end covers and partition plates for grouped installations. Verify torque settings on adjacent screw terminals if mixed connection types are used.
