Phoenix Contact PTI 2,5-L/L Borne de carril de instalación, multinivel, Push-in, 3 niveles, 24 A, 500 V, gris

Electricians and panel builders working on control cabinets and building installations often need to distribute power and signals across multiple levels without sacrificing space or clarity. The Phoenix Contact PTI 2,5-L/L installation multi-level terminal block answers that need with three stacked levels and six push-in connection points in a compact grey housing. It mounts on standard DIN rails NS 35/7,5 or NS 35/15, making it a direct fit for modern distribution boards and machine wiring.

Why choose it

Push-in technology cuts wiring time dramatically: simply insert a stripped solid conductor or a flexible conductor with ferrule and the spring clamp grips it securely. The three-level design packs six termination points into a width of just a few millimetres, freeing up rail space for other components. The polyamide housing is halogen-free and flame-retardant to UL 94 V0, so it meets strict fire safety requirements in building installations. With approvals from UL, cUL, VDE and EAC, this terminal block is accepted in projects across Europe, North America and beyond.

Ideal use cases

• Distribution boards in residential and commercial buildings
• Control cabinets for machine building and automation
• Signal and power distribution in HVAC and lighting systems
• Retrofitting existing installations where space is limited
• Panel shops that need fast, tool-free wiring for high-volume assembly

Good to know

The terminal block is part of the Phoenix Contact PTI series, known for its compact multi-level design and reliable spring connections. It is delivered in standard grey; other colours may be available on request. Always verify the maximum current and voltage against your specific application and local wiring regulations. The push-in mechanism is intended for solid conductors or flexible conductors with ferrules; for fine-stranded conductors without ferrules, use a screwdriver to open the clamp. The operating temperature range from -60 °C to +105 °C allows use in harsh environments, but the actual current rating may derate at higher ambient temperatures.
