M35/26.FF Entrelec Studded Power Terminal 25mm² Grey 1SNA115140R2300

The M35/26.FF (alternate code 1SNA115140R2300) is a studded power terminal block manufactured by TE Connectivity (Entrelec), rated at 101 A and designed for feedthrough connections up to 25 mm².

This grey 25 mm² studded feedthrough terminal block provides a robust, reliable connection point for high-current power circuits in industrial electrical installations. Featuring two M6 studs and cable lug termination in accordance with NF C 20-130 and DIN 46234, it is built for demanding environments where secure, vibration-resistant connections are essential.

Key Features

• 101 A current rating: Suitable for high-current power distribution circuits, reducing the risk of thermal overload at the terminal.
• Dual M6 studs: Two studs per block allow connection of cable lugs on both sides, enabling straightforward feedthrough wiring in power panels.
• Wide cable acceptance (2.5–25 mm² flexible / 2.5–50 mm² rigid): Accommodates a broad range of conductor sizes, offering flexibility across different installation requirements.
• Rated to 1000 V (IEC): Suitable for use across standard industrial voltage levels, including 400 V three-phase systems with ample safety margin.
• Rated short-time withstand current of 8000 A (1 s): Provides resilience against fault currents, protecting both the terminal and connected equipment.
• Universal DIN rail mounting (G32, TH35-7.5, TH35-15): Compatible with the most common rail types, simplifying integration into existing panel builds.
• Polyamide insulation body: High-quality thermoplastic construction provides excellent electrical isolation and mechanical durability across a wide operating temperature range (-55 °C to +110 °C).
• Spring washer design: Vibration-resistant spring washers maintain connection integrity in demanding environments without the need for retightening.

Applications

The M35/26.FF is well suited to industrial control panels, switchgear assemblies, and power distribution boards where high-current feedthrough connections are required. It is commonly used in manufacturing, process automation, and energy applications where large cross-section conductors must be terminated reliably on a DIN rail. The stud connection method — in compliance with NF C 20-130 and DIN 46234 — makes it a preferred choice where cable lug termination is specified, such as in motor control centres, power entry points, and heavy-duty distribution applications.

Standards and Sustainability

The M35/26.FF holds CE, cUL, and EAC certifications, complies with IEC 60715 for rail mounting, and is RoHS compliant in accordance with EU Directive 2011/65/EU.

Frequently Asked Questions

What cable sizes are compatible with the M35/26.FF terminal block?

The M35/26.FF accepts flexible conductors from 2.5 to 25 mm² and rigid conductors from 2.5 to 50 mm² per stud connection. Cable lugs should be tightened to 9 N·m as specified in the technical datasheet.

What DIN rail types does the M35/26.FF mount onto?

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

What is the voltage rating of the M35/26.FF?

The IEC rated voltage is 1000 V, with a UL/CSA maximum operating voltage of 600 V.

How does the stud connection method differ from a standard screw clamp terminal?

Rather than clamping bare wire directly, the M35/26.FF uses M6 threaded studs to secure cable lugs — making it better suited to high-current applications where a more secure, vibration-resistant mechanical connection is required.
