1sna400188r0300 – m10/10 black 10mm terminal

Why Choose the TE Connectivity M10/10 1SNA400188R0300 Feed-Through Terminal Block?

The TE Connectivity M10/10 1SNA400188R0300 is a black 10 mm² screw-clamp feed-through DIN rail terminal block from the ENTRELEC SNA range. Designed for dependable industrial signal and control wiring, it provides a straightforward two-position connection with a compact 10 mm terminal pitch.

The M10/10 uses proven screw-terminal connection technology with a specified tightening torque of 1.2 Nm. It accommodates flexible conductors from 0.5–10 mm² and rigid stranded conductors from 0.5–16 mm², providing useful flexibility for control panels, machinery and industrial electrical distribution.

With an IEC rating of 57 A at 1000 V, plus an 8 kV impulse withstand voltage and 1200 A short-time withstand current for 1 s, the M10/10 provides robust electrical performance. Its Polyamide 6.6 housing, IP20 protection and compatibility with G32 and TH35 DIN rails make it suitable for professional industrial terminal assemblies.
