Phoenix Contact PT 2,5 Push-in Feed-Through Terminal Block, 2.5 mm², Gray, DIN Rail Mount, 800 V, 24 A

In control cabinets and industrial distribution panels, electricians and panel builders rely on the Phoenix Contact PT 2,5 feed-through terminal block for fast, tool-free wiring of solid and stranded conductors up to 2.5 mm². Its push-in connection technology allows wires to be inserted directly without ferrules, cutting installation time significantly compared to screw terminals. The compact gray housing snaps onto standard 35 mm DIN rails, making it a staple in machine building, building automation, and power distribution applications where reliable, maintenance-free connections are essential.

Why choose it

The push-in connection eliminates the need for screwdrivers, reducing assembly time by up to 50% compared to traditional screw terminals. The high-quality polyamide housing is flame-retardant to UL 94 V0, ensuring safety in demanding industrial environments. Its wide operating temperature range from -60 °C to 105 °C makes it suitable for both cold storage and high-temperature applications. The terminal block's compact design saves space on the DIN rail, allowing for higher density wiring in control panels.

Ideal use cases

• Machine building and control cabinet wiring
• Building automation systems
• Power distribution in industrial panels
• Retrofit projects where quick, tool-free connections are needed
• Applications requiring maintenance-free connections

Good to know

The PT 2,5 terminal block is part of Phoenix Contact's comprehensive CLIPLINE complete system, offering a wide range of accessories such as end covers, partition plates, and marking options. It is designed for use with copper conductors only and complies with international standards including IEC 60947-7-1 and UL 1059.
