1sna400189r0400 – m10/10feedthrough term red

Why Choose the TE Connectivity M10/10 Red Feed-Through Terminal Block?

The TE Connectivity / ENTRELEC M10/10, manufacturer part number 1SNA400189R0400, is a robust red 10 mm² screw-clamp feed-through DIN rail terminal block designed for reliable conductor connection and potential distribution in industrial control panels, machinery and electrical installations. Part of the established ENTRELEC SNA series, it combines high current capacity with proven screw-clamp termination technology.

The M10/10 provides a straightforward single-level, two-position feed-through connection, allowing conductors on opposite sides of the terminal to be securely interconnected. Its red polyamide housing provides clear visual circuit identification, while the 10 mm terminal spacing delivers a compact installation footprint for its 10 mm² rated conductor size.

With an IEC rated current of 57 A, rated voltage of 1,000 V and impulse withstand voltage of 8,000 V, the 1SNA400189R0400 provides dependable electrical performance for industrial applications. It accommodates rigid stranded conductors up to 16 mm² and flexible conductors up to 10 mm², while compatibility with G32 and TH 35 DIN rails provides flexibility across new and existing panel installations.

Reliable High-Current Feed-Through Connections

Feed-through terminal blocks provide a secure electrical connection between conductors while creating an organised interface within a DIN rail assembly. The M10/10 uses a conventional screw-clamp mechanism that enables conductors to be installed, inspected and retightened using standard tools, making it a practical choice for industrial panels where dependable and serviceable wiring is required.

The 1SNA400189R0400 combines a 57 A IEC current rating with conductor capacity up to 16 mm² and a compact 10 mm terminal width. Its red housing allows installers to distinguish specific circuits or potentials from standard grey terminals, while compatibility with both G32 and TH 35 rails makes the M10/10 suitable for a wide range of existing and new electrical installations.

Typical Applications

• Industrial control and distribution panels.
• Machine building and OEM electrical systems.
• Factory automation and production equipment.
• Power and control circuit distribution.
• Motor control and machinery panels.
• Process control and instrumentation cabinets.
• Circuits requiring red terminal identification.
