Phoenix Contact PT 2,5-QUATTRO priechodová svorka, Push-in, 4-vodičová, 2,5 mm², 800 V, 24 A, sivá

In control cabinets and distribution boxes, electricians need a reliable way to distribute a single potential to multiple conductors without taking up excessive rail space. The Phoenix Contact PT 2,5-QUATTRO feed-through terminal block solves this with a compact, four-conductor design that uses push-in technology for fast, tool-free wiring. Its 2.5 mm² nominal cross-section handles 24 A at 800 V, making it suitable for a wide range of industrial and building automation circuits.

Key specifications

• Type: Feed-through terminal block, 1 level, 1 potential
• Connection: Push-in, 4 connections (QUATTRO)
• Nominal cross section: 2.5 mm² (solid: 0.14–4 mm²; flexible: 0.14–2.5 mm²; AWG 26–12)
• Rated voltage/current (IEC): 800 V / 24 A (max. 28 A with max conductor)
• Mounting: DIN rail NS 35/7,5 or NS 35/15
• Material: Polyamide (PA), flammability UL 94 V0
• Operating temperature: -60 °C to +105 °C
• Stripping length: 8–10 mm
• Colour: Grey

Why choose it

Push-in connections reduce wiring time by up to 50% compared to screw terminals—no ferrules required for solid or stranded conductors with appropriate preparation. The QUATTRO design lets you connect four conductors to a single potential, saving space on the DIN rail and simplifying potential distribution. The PA housing is halogen-free and flame-retardant, ensuring safety in densely packed enclosures. Phoenix Contact's proven spring-cage technology guarantees vibration-resistant, maintenance-free connections over the product's lifetime.

Ideal use cases

• Potential distribution in control panels and machine wiring
• Building automation systems (lighting, HVAC, access control)
• Power supply distribution to multiple sensors or actuators
• Retrofit projects where fast, tool-free installation is critical
• Applications with high vibration or temperature cycling

Good to know

The terminal block is part of the CLIPLINE complete system, compatible with standard Phoenix Contact accessories such as end covers, partition plates, and marking tags. It is rated for use in potentially explosive atmospheres (ATEX) when installed according to the manufacturer's instructions. The grey colour is standard for feed-through terminals, allowing easy visual identification in the cabinet. For larger conductor cross-sections or higher currents, consider the PT 4 or PT 6 series.
