1sna399031r2200 – d1/5.p.ado

Why Choose the TE Connectivity D1/5.P.ADO 1SNA399031R2200 Ground Terminal Block?

The TE Connectivity D1/5.P.ADO 1SNA399031R2200 is a compact ground terminal block with ADO connections, designed to provide dependable protective conductor connections in industrial control panels, machinery and electrical distribution systems. Part of the established Entrelec SNA ADO terminal block range, it combines fast conductor termination with a secure, screwless connection to the DIN rail.

This green-yellow protective earth terminal features ADO connections on both sides and a rated conductor cross-section of 1 mm². The ADO insulation-displacement connection system allows conductors to be terminated efficiently while providing consistent electrical contact, making the terminal particularly suitable for high-density panel wiring and repetitive industrial assembly.

With a compact 5 mm spacing, the D1/5.P.ADO helps maximise available DIN-rail space. It mounts on standard TH 35-7.5 and TH 35-15 DIN rails, provides IP20 protection at the main terminals and incorporates a screwless rail contact for reliable protective earth continuity.

Reliable Protective Earth Connections with ADO Technology

Protective earth terminals provide the connection between equipment conductors and the grounded DIN rail, helping maintain a reliable path for fault current in industrial electrical systems. The D1/5.P.ADO uses a screwless rail contact that does not depend on operator-applied tightening torque, supporting consistent installation and secure grounding.

TE Connectivity's ADO insulation-displacement system is designed for rapid conductor termination without a conventional screw-clamp connection. Combined with the terminal's compact 5 mm width, this makes the D1/5.P.ADO particularly useful in densely populated control cabinets where fast assembly, reliable grounding and efficient use of DIN-rail space are important.

Typical Applications

• Protective earth connections in industrial control panels.
• Machine-building and factory automation systems.
• Switchgear and electrical distribution assemblies.
• PLC and automation control cabinets.
• Industrial equipment grounding circuits.
• High-density DIN-rail terminal installations.
