1SNA199235R2300 – DR4/6.SNT2.ADO [pack 50]

Why Choose the TE Connectivity D4/6.SNT2.ADO Disconnect Terminal Block?

The TE Connectivity D4/6.SNT2.ADO (1SNA199235R2300) is a compact knife-disconnect terminal block with two integrated test sockets, designed for industrial control, measurement and automation circuits requiring convenient isolation and testing. Part of the TE Connectivity ENTRELEC ADO System, it combines an ADO insulation-displacement connection with a conventional screw-clamp connection in a narrow DIN rail format.

A manually operated disconnect knife blade allows the electrical circuit to be opened directly at the terminal without removing connected conductors. Two integrated 2 mm test sockets provide accessible points for electrical measurements during commissioning, diagnostics and maintenance, making the terminal particularly useful in control and instrumentation circuits that require regular testing.

The D4/6.SNT2.ADO has a rated cross-section of 1.5 mm², a rated current of 10 A and a rated voltage of 500 V. Its compact 6 mm spacing, mixed ADO/screw-clamp termination and TH35 DIN rail mounting provide a versatile connection solution for densely populated industrial panels.

Key Advantages

• Hand-operated knife disconnect enables convenient individual circuit isolation.
• Two integrated 2 mm test sockets provide accessible measurement points.
• Combines ADO insulation-displacement and screw-clamp termination in one terminal.

Reliable Circuit Isolation with ADO and Screw-Clamp Termination

The D4/6.SNT2.ADO provides a practical means of opening individual electrical circuits without removing their conductors from the terminal strip. Its hand-operated knife blade creates a clear mechanical disconnect point, helping technicians perform commissioning, fault-finding and maintenance procedures efficiently.

The mixed connection arrangement combines the advantages of the ADO insulation-displacement system with a standard screw clamp, allowing different conductor termination methods within the same terminal. Together with the two 2 mm test sockets and compact 6 mm width, this makes the 1SNA199235R2300 particularly useful for measurement, control and instrumentation circuits where accessible testing and isolation are important.

Typical Applications

• Industrial electrical control panels.
• PLC and automation cabinets.
• Measurement and instrumentation circuits.
• Process control systems.
• Machine control and auxiliary wiring.
• Circuits requiring individual isolation and testing.
• Commissioning and diagnostic terminal assemblies.
• OEM machinery and industrial panel building.
