Why Choose the TE Connectivity M16/12 White Feed-Through Terminal Block?

The TE Connectivity M16/12, part number 1SNA400193R2000, is a white screw-clamp feed-through terminal block from the Entrelec SNA range. Designed for dependable conductor-to-conductor connections, it provides two screw-terminal positions on a single level and is suitable for signal and general industrial electrical wiring.

With a rated conductor size of 16 mm², an IEC rated current of 76 A and an IEC rated voltage of 1000 V, the M16/12 provides robust electrical performance in a compact 12 mm terminal width. Its screw-clamp connections accommodate flexible conductors from 2.5–16 mm² and rigid stranded conductors from 2.5–25 mm².

The terminal mounts on G32, TH 35-7.5 and TH 35-15 rails, providing flexibility when integrating it into new or existing control panels. A Polyamide 6.6 housing, UL 94V-0 flammability rating and IP20 protection support reliable use across professional industrial electrical assemblies.

Reliable High-Current Screw-Clamp Feed-Through Wiring

The M16/12 provides a straightforward single-circuit feed-through connection using proven screw-clamp technology. Its conductor capacity allows flexible wires up to 16 mm² and rigid stranded conductors up to 25 mm² to be terminated, while the specified 14 mm stripping length and 1.2 N·m tightening torque support consistent installation.

Electrical ratings of 76 A at 1000 V under IEC specifications, together with an 8 kV impulse withstand rating and 1920 A for 1 s short-time withstand capability, make the terminal suitable for robust industrial wiring. Compatibility with both symmetrical TH 35 rails and G32 rail further increases installation flexibility.

Typical Applications

• Industrial control and automation panels.
• Machinery and equipment wiring.
• High-current feed-through conductor connections.
• Signal and control circuit terminal assemblies.
• Electrical distribution and switchgear cabinets.
• G32 and TH 35 DIN rail terminal installations.
