1SNA115479r2300 – t/block 6mm 2in 2out m4/6.4a

Why Choose the TE Connectivity M4/6.4A 1SNA115479R2300 2-In 2-Out Terminal Block?

The TE Connectivity M4/6.4A 1SNA115479R2300 is a grey 4-connection feed-through screw clamp terminal block designed for industrial signal and control wiring. Part of the established TE Connectivity ENTRELEC SNA series, its multiclamp configuration provides two conductor connections on each side, making it an effective 2-in, 2-out terminal block for distributing a single electrical circuit between multiple conductors.

The M4/6.4A combines four poles within one circuit and uses proven screw clamp termination to provide secure, maintainable electrical connections. Its multi-connection arrangement can simplify panel wiring where several conductors need to share the same potential, reducing the need to double-up conductors within individual clamps or add separate distribution terminals.

With a 4 mm² rated conductor size, 32 A IEC current rating and 800 V IEC voltage rating, the M4/6.4A provides substantial electrical capability within a compact 6 mm width. It supports flexible conductors from 0.22–4 mm², rigid stranded conductors from 0.2–4 mm² and mounting on G32, TH35-7.5 and TH35-15 DIN rails.

Four Connections in a Compact 6 mm Terminal

Multi-connection feed-through terminals are useful where several conductors need to be connected to the same electrical potential without installing separate terminals and external bridging. The M4/6.4A provides four connections within one feed-through circuit, making it particularly suitable for 2-in, 2-out wiring arrangements and other applications requiring multiple common conductor connections.

Its combination of 32 A IEC current capacity, 800 V IEC voltage rating and a compact 6 mm footprint provides strong electrical performance without consuming excessive DIN rail space. Screw clamp termination, polyamide 6.6 insulation and an operating temperature range extending from -55 to +110 °C further support dependable use in industrial control and automation equipment.

Typical Applications

• 2-in, 2-out industrial wiring connections.
• PLC and automation control cabinets.
• Signal and control circuit distribution.
• Industrial machinery and production equipment.
• Common-potential conductor connections.
• High-density DIN rail terminal assemblies.
• OEM electrical and control panel systems.
