Why Choose the TE Connectivity D2.5/5.SN.ADO Disconnect Terminal Block?
The TE Connectivity D2.5/5.SN.ADO, part number 1SNA399226R0200, is a compact disconnect terminal block with ADO and screw-clamp connections designed for measurement, control and industrial wiring applications. Part of the established Entrelec SNA terminal block range, it combines a manually operated disconnect blade with an integrated test socket for convenient circuit isolation and testing.
The terminal uses the ADO insulation displacement connection system on one side and a conventional screw clamp on the other, providing flexibility when terminating different conductor arrangements. The ADO connection supports fast wiring without conductor stripping while the screw-clamp side accommodates a wider conductor range for integration into standard control-panel wiring.
With a rated current of 10 A, rated voltage of 320 V and rated cross-section of 1 mm², the D2.5/5.SN.ADO provides dependable circuit separation in a compact 5 mm terminal width. A 2 mm test socket on the ADO side enables convenient electrical measurements without dismantling the wiring.
Key Advantages
- Integrated hand-operated disconnect blade for convenient circuit isolation.
- Combination of ADO and screw-clamp connection technologies.
- Integrated 2 mm test socket for measurement and diagnostics.
- 10 A rated current and 320 V rated voltage.
- Compact 5 mm width helps maximise DIN rail space.
- Supports up to two conductors per ADO connection point.
Key Features
- TE Connectivity / Entrelec SNA series.
- D2.5/5.SN.ADO disconnect terminal block.
- Manual knife-blade disconnect mechanism.
- ADO insulation displacement connection combined with screw clamp.
- 2 mm diameter test socket on the ADO side.
- 1 mm² rated cross-section.
- 5 mm terminal width.

- Compatible with TH 35-7.5 and TH 35-15 DIN rails.
Reliable Disconnect and Testing for Control Circuits
Disconnect terminal blocks provide a convenient way to isolate individual circuits without removing conductors from the terminal. The manually operated blade in the D2.5/5.SN.ADO allows technicians to open the electrical path for commissioning, troubleshooting and maintenance, while the integrated test socket provides direct access for measurement equipment.
The combination of ADO and screw-clamp technologies also makes the terminal particularly versatile. The ADO connection provides fast insulation-displacement termination, while the screw-clamp side accommodates conventional prepared conductors, making the terminal suitable for mixed wiring practices in industrial control and instrumentation systems.
