Why Choose the TE Connectivity 1SNA125166R1300 M4/6.D1.N Blue Double-Level Terminal Block?

The TE Connectivity 1SNA125166R1300, manufacturer designation M4/6.D1.N, is a blue double-level feed-through screw-clamp terminal block from the Entrelec SNA range. Designed for DIN rail installation, it combines two connection levels within a compact 6 mm width, making it well suited to high-density industrial control and signal wiring.

The terminal block provides a rated IEC current of 32 A and a rated IEC voltage of 800 V, with conductor capacity up to 4 mm² / 10 AWG. Screw-terminal technology provides a familiar and dependable connection method, while the double-level construction helps increase wiring density without requiring additional DIN rail length.

Manufactured with a polyamide 6.6 housing, the M4/6.D1.N is rated IP20 and uses material meeting UL 94V-0 flammability requirements. It mounts on G32, TH35-7.5 and TH35-15 DIN rails and is designed for an operating temperature range from -55 to +110 °C, supporting demanding industrial panel applications.

Key Advantages

• Double-level construction increases connection density within a 6 mm terminal width.
• Rated up to 32 A at 800 V IEC for industrial electrical and signal circuits.
• Accepts conductors up to 4 mm² / 10 AWG.
• Reliable screw-clamp termination with a specified tightening torque of 0.5 Nm.
• Compatible with G32 and both common TH35 DIN rail profiles.
• Wide -55 to +110 °C operating temperature range for demanding environments.

Key Features

• TE Connectivity / Entrelec M4/6.D1.N modular terminal block.
• Blue housing for circuit identification.
• 2-level, 2-position feed-through configuration.
• 6 mm product spacing.
• 32 A IEC current rating.
• 800 V IEC voltage rating and 8 kV impulse withstand rating.
• Polyamide 6.6 housing with UL 94V-0 flammability rating.
• IP20 protection rating.

Space-Efficient Double-Level Feed-Through Connection

Double-level terminal blocks allow two connection levels to occupy the DIN rail space normally associated with a single-width terminal position. The M4/6.D1.N therefore provides a practical solution for panels containing large numbers of signal or control conductors, helping panel builders increase wiring density while maintaining accessible screw connections.

With a 32 A IEC current rating, 800 V IEC voltage rating and conductor capacity up to 4 mm², the 1SNA125166R1300 combines compact dimensions with robust electrical performance. Compatibility with G32 and TH35 rail systems further supports its use in new equipment, panel extensions and maintenance of established Entrelec SNA installations.

Typical Applications

• Industrial electrical control panels.
• High-density signal and control wiring.
• PLC and industrial automation cabinets.
• Machine control systems and production equipment.
• Instrumentation and process-control panels.
• OEM panel building and Entrelec SNA terminal system maintenance.
