Phoenix 3213962 PTI 2,5-PE Push-in-aardklem, 2,5 mm², groen-geel, DIN-railmontage

In industrial control panels and building installations, electricians need a reliable way to terminate protective earth conductors quickly without tools. The Phoenix 3213962 PTI 2,5-PE ground terminal block answers that need with push-in connection technology: simply insert a solid or stranded conductor with ferrule and it locks securely. Rated for 2.5 mm² nominal cross section and green-yellow colour coding for PE identification, this terminal block mounts on standard DIN rails NS 35/7,5 or NS 35/15. It provides one ground position with two connection points, ensuring a low-resistance earth path in distribution boards, machine wiring, and automation systems.

Key specifications

• Connection technology: Push-in, tool-free wiring for solid and stranded conductors with ferrule
• Nominal cross section: 2.5 mm², supports solid 0.2–4 mm² and stranded 0.2–2.5 mm²
• Colour: Green-yellow (standard PE identification)
• Number of connections: 2 (one ground position)
• Mounting type: DIN rail NS 35/7,5 and NS 35/15
• Insulating material: Polyamide (PA), flammability rating UL 94 V0
• Stripping length: 8–10 mm
• Operating temperature: -60 °C to +105 °C
• Rated surge voltage: 6 kV, overvoltage category III, pollution degree 3
• Standards and approvals: IEC 60947-7-2, UL, cUL, EAC, VDE

Why choose it

The push-in mechanism reduces wiring time by up to 50% compared to screw terminals, while the vibration-resistant contact ensures long-term reliability in harsh industrial environments. The green-yellow housing clearly marks the terminal as protective earth, preventing wiring errors. With a wide operating temperature range and high surge voltage rating, it is suitable for demanding applications from cold storage to solar inverters.

Ideal use cases

• Terminating PE conductors in control cabinets and distribution boards
• Building automation and HVAC systems requiring quick, tool-free installation
• Machine building and panel shops where wiring speed and reliability are critical
• Railway and renewable energy installations with vibration and temperature extremes

Good to know

For stranded conductors without ferrules, push-in terminals require a screwdriver to open the spring cage. The terminal block is part of the Phoenix Contact PTI series, known for compact design and high density on the DIN rail. Always verify the maximum current rating according to the installation standard and ambient temperature derating.
