MA2.5/5.P Entrelec Ground Terminal 2.5mm² 1SNA165488R2700

The MA2.5/5.P (alternate code 1SNA165488R2700) is a 2.5mm² screw clamp ground terminal block manufactured by TE Connectivity (Entrelec), designed to provide a reliable earth connection within DIN rail-mounted terminal assemblies.

This green and yellow ground terminal block offers a secure, low-maintenance screw clamp connection for earthing conductors in control panels and industrial wiring installations. Its asymmetrical design and snap-fit mounting make it quick to install, while its profile is aligned with the MA2.5/5 feed-through terminal for a neat, consistent assembly.

Key Features

• Screw clamp connection: Provides a reliable, vibration-resistant termination with a tightening torque of 0.4–0.6 Nm — no retightening campaigns required thanks to TE Connectivity's anti-release design.
• Wide conductor compatibility: Accepts flexible conductors from 0.22–2.5mm² and rigid/stranded conductors from 0.2–4mm², giving flexibility across a range of cable types and sizes.
• Universal DIN rail mounting: Snaps onto G32, TH35-7.5, and TH35-15 rails, making it suitable for virtually any standard industrial enclosure or panel build.
• Polyamide 6.6 housing (UL 94V-0): The high-grade flameretardant insulation material ensures safety and durability in demanding environments.
• Green/yellow identification: Immediately identifiable as an earth terminal, supporting safe and compliant panel wiring practice.
• Compact 5mm pitch: Maximises terminal density within the panel, with a profile that sits flush alongside the MA2.5/5 feed-through range.
• 300A short-time withstand current (1s): Rated for fault conditions, providing confidence in panel safety and performance under transient overloads.

Applications

The MA2.5/5.P is used wherever a dedicated earth connection is required within DIN rail terminal assemblies. Typical applications include industrial control panels, machine building, process automation, and power distribution enclosures across manufacturing, infrastructure, and building services sectors. It is particularly well suited for use alongside MA2.5/5 feed-through terminals, allowing mixed earth and signal/power terminal rows to be built with a consistent profile and pitch.

Standards and Compliance

The MA2.5/5.P holds CE, cULus, CSA, EAC, and RMRS certifications, complies with RoHS (EU Directive 2002/95/EC), and the housing meets UL 94V-0 flammability requirements.

Frequently Asked Questions

What cable sizes are compatible with the MA2.5/5.P ground terminal?

It accepts flexible conductors from 0.22–2.5mm² and rigid or stranded conductors from 0.2–4mm², with a wire stripping length of 10mm.

What DIN rails is the MA2.5/5.P compatible with?

It mounts on G32 (32×15mm), TH35-7.5 (35×7.5mm), and TH35-15 (35×15mm) rails in accordance with IEC 60715.

What is the correct tightening torque for the MA2.5/5.P?

The IEC-rated tightening torque is 0.4 Nm; the manufacturer's recommended maximum is 0.6 Nm. A 3.5mm flat-blade screwdriver should be used.

How does the MA2.5/5.P differ from the MA2.5/5?

The MA2.5/5.P is a dedicated ground terminal finished in green and yellow with a connection to the DIN rail for earthing, whereas the MA2.5/5 is a standard grey feed-through terminal. Both share the same 5mm pitch and profile, so they can be used side by side in the same assembly.
