M4/6 Entrelec Grey Feedthrough Terminal 4mm² 1SNA115116R0700

The M4/6 (also known as 1SNA115116R0700) is a grey 4mm² feedthrough screw clamp terminal block from Entrelec, manufactured by TE Connectivity, rated at 32A and 1000V — suitable for a wide range of industrial panel-building applications.

The M4/6 is a single-level feedthrough terminal block designed for reliable DIN rail-mounted wire connections in electrical control panels and industrial enclosures. Built with TE Connectivity's proven screw clamp technology, it delivers secure, vibration-resistant connections that minimise the need for retightening. The compact 6mm pitch makes it ideal for high-density wiring installations.

Key Features

• 32A / 1000V Rating: Suitable for demanding industrial circuits, with a short-time withstand current of 480A at 1s for added fault tolerance.
• Screw Clamp Connection: TE Connectivity's exclusive anti-release design locks the screw securely, resisting accidental loosening from vibration or cable stress — no retightening campaigns needed.
• Wide Cable Acceptance: Accepts rigid conductors from 0.2–4mm² and flexible conductors from 0.22–4mm², plus insulated ferrules up to 2.5mm², giving flexibility across different wiring configurations.
• Multi-Rail Mounting: Snaps onto G32, TH35-7.5, and TH35-15 DIN rails — both symmetrical and asymmetrical — for versatile panel assembly.
• IP20 Protection: Provides finger protection against accidental contact, meeting IEC 60529 requirements for panel installations.
• UL 94V-0 Rated Polyamide 6.6 Housing: Flame-retardant insulation material ensures safety even in demanding electrical environments.
• Compact 6mm Pitch: Space-saving design allows high-density terminal arrangements without compromising accessibility or safety.
• Multiple Colour Options Available: Grey is the standard; additional colours can be used for quick visual identification of circuit functions within a panel.

Applications

The Entrelec M4/6 is well suited to industrial control panels, machine building, power distribution boards, and process automation enclosures. It is widely used across manufacturing, building services, energy, and infrastructure sectors where reliable, space-efficient conductor termination is essential. The terminal block is particularly appropriate where multi-rail compatibility and high connection integrity under vibration are required.

Standards & Compliance

The M4/6 holds CE, cUL, CSA, EAC, and RMRS certifications, complies with IEC 60947-1 and IEC 60529, and is RoHS compliant in accordance with EU Directive 2002/95/EC.

Frequently Asked Questions

What cable sizes can be connected to the M4/6 terminal block?

The M4/6 accepts rigid or stranded conductors from 0.2–4mm² and flexible conductors from 0.22–4mm², with insulated ferrules up to 2.5mm². Wire stripping length is 9.5mm.

What DIN rails is the M4/6 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 — both symmetrical and asymmetrical profiles.

What is the correct tightening torque for the M4/6?

Per IEC 60947-1, the minimum tightening torque is 0.5Nm; the manufacturer-recommended maximum is 0.8Nm. Use a 4mm flat-blade screwdriver.

How does the M4/6 differ from the MA2.5/5 terminal block?

The M4/6 is rated for 4mm² conductors at 32A with a 6mm pitch, whereas the MA2.5/5 is rated for 2.5mm² at 24A with a narrower 5mm pitch — choose based on your current and conductor size requirements.
