M4/6.N Entrelec Feedthrough Terminal 4mm² Blue 1SNA125116R0100

The M4/6.N (alternate code 1SNA125116R0100) is a 4mm² blue feedthrough terminal block from Entrelec, manufactured by TE Connectivity, rated at 32A and designed for screw clamp DIN rail installation.

The Entrelec M4/6.N is a single-level, feed-through screw clamp terminal block suitable for a wide range of industrial wiring and panel-building applications. Its blue colour coding allows quick visual identification of specific circuit functions within control panels and enclosures. Built on TE Connectivity's proven screw clamp technology, it delivers reliable, vibration-resistant connections in demanding environments.

Key Features

• 32A Current Rating at 4mm²: Suitable for a broad range of industrial control and power circuits without oversizing the terminal block.
• Screw Clamp Connection: TE Connectivity's exclusive anti-release design resists loosening from vibration and shock, reducing the need for retightening campaigns.
• Universal DIN Rail Mounting: Snaps onto G32, TH35-7.5, and TH35-15 rails, offering flexibility across different panel configurations.
• Blue Colour Coding: Enables fast visual identification of specific circuit functions within a terminal rail assembly.
• Wide Conductor Compatibility: Accepts rigid conductors from 0.2–4mm² and flexible conductors from 0.22–4mm², accommodating varied wiring practices.
• 1000V Rated Voltage: Suitable for high-voltage industrial applications up to 1000VAC, with an impulse withstand voltage of 8000V.
• IP20 Protection: Provides finger protection against contact with live parts, meeting standard panel safety requirements.
• Polyamide 6.6 (PA6.6) Housing: UL 94V-0 rated flame-retardant material ensures safety and long-term durability in industrial enclosures.

Applications

The M4/6.N feedthrough terminal block is widely used in industrial control panels, machine building, process automation, and electrical distribution enclosures. The blue colouring makes it particularly suited for neutral conductor identification or any application where colour-coded circuit segregation is required. It is compatible with a comprehensive range of accessories including jumper bars, end stops, circuit separators, and marking systems, making it a versatile choice for panel builders and electrical installers across manufacturing, building services, and infrastructure sectors.

Standards & Sustainability

The M4/6.N carries CE, RoHS, CSA, and EAC certifications, complies with IEC 60529 (IP20) and IEC 60947-1, and is manufactured in accordance with ISO 9001 and ISO 14001 environmental management standards.
