1SNA199456R2100 – M4/6,D2,S1,RT

Why Choose the TE Connectivity M4/6.D2.S1R.T Terminal Block 1SNA199456R2100?

The TE Connectivity 1SNA199456R2100, type M4/6.D2.S1R.T, is a specialised double-level disconnect screw-clamp terminal block from the ENTRELEC SNA range, designed for switching, signal routing and test applications in industrial control and automation systems. Its pull-lever changeover arrangement allows a signal to be directed between the upper and lower terminal levels with a single operation.

Designed for efficient testing and maintenance, the M4/6.D2.S1R.T incorporates three test sockets that provide convenient access for electrical measurements. The closed terminal-block construction eliminates the need for a separate end section, while the compact 6 mm spacing helps maximise wiring density inside control cabinets.

With a 10 A rated current, 500 V rated voltage and 4 mm² rated cross-section, the 1SNA199456R2100 provides a robust solution for control and measurement circuits. Screw-clamp connections accept flexible and rigid conductors up to 4 mm², while compatibility with G32 and TH35 DIN rails provides installation flexibility across industrial panel systems.

Flexible Signal Switching and Testing for Control Circuits

Disconnect and changeover terminal blocks provide technicians with convenient control over electrical circuits without requiring conductors to be removed from the terminal assembly. The M4/6.D2.S1R.T uses a pull-lever mechanism to direct a signal either to the upper level when the lever is in its high position or to the lower level when the lever is moved to its low position.

Integrated test sockets make the terminal particularly useful in measurement, commissioning and maintenance applications, providing accessible points for diagnostic equipment. Its double-level construction also makes efficient use of DIN rail space, while screw-clamp connections provide dependable conductor termination in industrial control and automation environments.

Typical Applications

• Industrial control and automation panels.
• Signal switching and changeover circuits.
• Measurement and test circuits.
• PLC and instrumentation cabinets.
• Process control systems.
• Machine control and OEM equipment.
• Electrical panels requiring accessible circuit test points.
• High-density double-level terminal assemblies.
