M10/10 Entrelec Grey Feedthrough Terminal 10mm² 1SNA115120R1700

The M10/10 (alternate code 1SNA115120R1700) is a 10mm² grey feedthrough screw clamp terminal block from Entrelec, manufactured by TE Connectivity, rated at 57A and 1000V for reliable single-level feed-through connections on DIN rail assemblies.

The M10/10 is a robust, single-level feedthrough terminal block designed for industrial control panels and electrical installations requiring secure, high-current wire connections. Built on TE Connectivity's proven screw clamp technology, it offers dependable performance across a wide range of industrial applications where vibration resistance and connection integrity are critical.

Key Features

• 57A Current Rating at 1000V: Suitable for demanding power circuits, with a short-time withstand current of 1200A at 1s for fault tolerance.
• Screw Clamp Connection: TE Connectivity's exclusive anti-release design resists loosening from vibration and shock, reducing the need for retightening campaigns.
• Wide Cable Acceptance: Accepts rigid/stranded conductors from 0.5–16mm² and flexible conductors from 0.5–10mm², giving flexibility across different wiring configurations.
• Universal DIN Rail Mounting: Compatible with G32, TH35-7.5, and TH35-15 rails — snaps onto both symmetrical and asymmetrical rails for fast, tool-free installation.
• Polyamide 6.6 Construction: UL 94V-0 rated housing provides excellent flame resistance and durability in industrial environments.
• IP20 Protection: Main terminals are protected to IP20, suitable for use within enclosed control panels and switchgear.
• 8000V Impulse Withstand Voltage: Provides strong dielectric resilience, supporting safe use in high-voltage transient environments.

Applications

The M10/10 is well suited to industrial control panels, machine building, power distribution assemblies, and process automation installations. It is commonly used where 10mm² conductors need to be terminated cleanly and securely on DIN rail — including motor control panels, HVAC systems, and general electrical enclosures. The terminal block's compatibility with multiple rail types makes it a practical choice across a broad range of panel-building and switchgear applications.

Standards and Compliance

The M10/10 holds CE, RoHS, cUL, and CSA certifications, with degree of protection to IP20 per IEC 60529 and IEC 60947-1, and flammability rating UL 94V-0.
