Why Choose the TE Connectivity 1SNA125121R0600 M10/10.NT Terminal Block?
The TE Connectivity 1SNA125121R0600, also designated M10/10.NT, is a blue interruptible neutral terminal block designed for reliable neutral conductor connection and disconnection within industrial electrical panels. Part of the established Entrelec SNA terminal block range, it combines screw-clamp conductor termination with a sliding-link neutral disconnect function for convenient circuit isolation.
Designed around a 10 mm² rated cross-section, the M10/10.NT accommodates flexible conductors from 0.5–10 mm² and rigid conductors from 0.5–16 mm². Its blue insulation provides clear visual identification of neutral circuits, while the disconnect arrangement allows maintenance and testing without unnecessarily disturbing adjacent wiring.
With an IEC rated current of 57 A and rated voltage of 400 V, this terminal block is suitable for demanding control-panel and power-distribution applications. Its versatile mounting system supports G32, TH35-7.5 and TH35-15 DIN rails, making it straightforward to integrate into new or existing panel assemblies.

Reliable Neutral Distribution and Isolation
Neutral disconnect terminals are used where neutral conductors need to remain securely terminated while also providing a practical means of isolation for testing, commissioning and maintenance. The M10/10.NT incorporates a sliding-link disconnect arrangement that enables the neutral circuit to be interrupted without removing the connected conductor.
The screw-clamp connection technology provides a strong and dependable electrical connection, while the terminal's compatibility with standard DIN rail systems simplifies installation alongside other SNA series terminal blocks. Its blue housing also supports clear circuit identification in densely populated industrial control panels.
Typical Applications
- Industrial electrical control panels.
- Neutral conductor distribution and isolation.
- Power distribution boards.
- Machine control cabinets.
- Automation and process-control systems.
- Electrical testing and maintenance circuits.
- OEM machinery and panel-building applications.
