M6/8.N Entrelec Feedthrough Terminal 6mm² Blue 1SNA125118R1300

The M6/8.N (alternate code 1SNA125118R1300) is a 6mm² blue feedthrough screw clamp terminal block from Entrelec by TE Connectivity, rated at 41A and 1000V for reliable DIN rail wiring applications.

The M6/8.N is a single-level feedthrough terminal block designed for efficient conductor interconnection in industrial control panels and electrical enclosures. Built with a proven screw clamp connection system, it delivers a secure, vibration-resistant connection that minimises the need for re-tightening campaigns. The blue colouring enables quick visual identification of specific circuits or functions within a panel.

Key Features

• 41A current rating at 1000V: Suitable for a wide range of industrial control and power distribution circuits.
• Screw clamp connection: TE Connectivity's exclusive anti-release design uses overlapping tabs to lock the clamp, preventing accidental loosening due to vibration or cable pull.
• Flexible conductor range (0.5–6mm² / rigid up to 10mm²): Accommodates a broad range of cable sizes including flexible, solid, and insulated ferrule terminations up to 6mm².
• Universal DIN rail mounting: Snaps onto G32, TH35-7.5, and TH35-15 rails, giving installers flexibility across different panel configurations.
• Blue colour coding: Enables fast identification of specific circuit functions alongside grey standard terminals, reducing wiring errors.
• IP20 protection (Polyamide 6.6 housing): UL 94V-0 rated flammability for safe use in enclosed panel environments.
• 8mm pitch spacing: Compact footprint helps maximise terminal density within the enclosure.
• 720A short-time withstand current (1s): Provides resilience against transient fault currents, protecting the installation integrity.

Applications

The M6/8.N feedthrough terminal block is widely used in industrial control panels, machine building, process automation, and electrical distribution boards. It is suited to applications where circuit identification by colour is important, such as multi-function panels combining power, control, and signal wiring. The terminal's universal rail compatibility makes it a practical choice for panel builders working across varied enclosure types.

Standards & Compliance

The M6/8.N carries CE, RoHS, cUL, and CSA certifications, complies with IEC 60529 and IEC 60947-1, and is manufactured in accordance with EU environmental directives.

Manufactured by TE Connectivity (Entrelec), country of origin: France. Order code: M6/8.N / 1SNA125118R1300.

Frequently Asked Questions

What cable sizes are compatible with the M6/8.N terminal block?

It accepts rigid/stranded conductors from 0.5–10mm² and flexible conductors from 0.5–6mm², with a wire stripping length of 12mm. Insulated ferrules up to 6mm² are also supported.

What DIN rail types does the M6/8.N mount onto?

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

What is the correct tightening torque for the M6/8.N?

The IEC-rated tightening torque is 0.8 N·m, with a manufacturer maximum of 1 N·m. A 4.5mm flat-blade screwdriver is recommended.

How does the blue M6/8.N differ from the standard grey version?

The electrical and mechanical specifications are identical — the blue colour is used purely for circuit identification, helping engineers quickly distinguish specific functions within a panel.
