M4/6.D2 Entrelec Grey Double Deck Terminal 4mm² 1SNA115271R2200

The M4/6.D2 (alternate code 1SNA115271R2200) is a grey double deck screw clamp terminal block manufactured by TE Connectivity (Entrelec), rated at 32 A and 800 V, with a compact 6 mm spacing.

The Entrelec M4/6.D2 is a 4 mm² double deck feedthrough terminal block designed to deliver two fully independent circuits within a single 6 mm wide block, making it ideal for high-density wiring in electrical control panels. Its screw clamp connection technology — refined over decades — provides a secure, vibration-resistant termination that minimises the need for retightening campaigns.

Key Features

• Double deck, two independent circuits: Accommodates two separate connections in just 6 mm of rail space, significantly reducing panel footprint without sacrificing functionality.
• 32 A / 800 V rated: Suitable for demanding industrial applications, with a short-time withstand current of 480 A at 1 second.
• Universal rail mounting: Snaps onto G32, TH35-7.5, and TH35-15 DIN rails — symmetrical and asymmetrical — for flexible installation.
• Wide conductor range: Accepts flexible conductors from 0.22–4 mm² and rigid/stranded from 0.2–4 mm² (22–12 AWG), accommodating a broad range of cable sizes.
• Polyamide 6.6 construction: UL 94 V-0 rated insulation material offers excellent flame resistance and long-term mechanical durability.
• IP20 protection: Provides finger-safe access and compliance with IEC 60529 and IEC 60947-1, suitable for panel environments.
• Impulse withstand voltage of 8,000 V: Offers robust insulation performance for reliable operation in electrically demanding environments.

Applications

The M4/6.D2 is well suited to industrial control panels, machine building, and process automation where rail space is at a premium. Its double deck configuration is particularly useful where multiple signal or control circuits must be routed in a compact enclosure, such as in manufacturing plant switchgear, motor control panels, and building automation systems.

Standards and Compliance

The M4/6.D2 holds CE, cUL, EAC, and RMRS certifications, complies with IEC 60529 and IEC 60947-1, meets UL 94 V-0 flammability requirements, and is RoHS compliant in accordance with EU Directive 2002/95/EC.

Frequently Asked Questions

What cable sizes can be used with the M4/6.D2?

The M4/6.D2 accepts flexible conductors from 0.22–4 mm² and rigid/stranded conductors from 0.2–4 mm² per clamp, equivalent to 22–12 AWG.

What DIN rails is the M4/6.D2 compatible with?

It mounts onto G32, TH35-7.5, and TH35-15 rails in accordance with IEC 60715, supporting both symmetrical and asymmetrical rail types.

What is the correct tightening torque for the M4/6.D2?

The IEC-specified tightening torque is 0.5 Nm, with a manufacturer maximum of 0.8 Nm, using a 4 mm flat-head screwdriver.

How does the M4/6.D2 differ from the standard M4/6 feedthrough terminal?

Unlike the single-deck M4/6, the M4/6.D2 features two independent circuits stacked within the same 6 mm spacing, effectively doubling the connection density on the rail.
