Why Choose the TE Connectivity DR4/6.ADO Terminal Block?
The TE Connectivity DR4/6.ADO is a compact feed-through ADO/Screw terminal block designed for reliable electrical connections in industrial control panels, automation systems and electrical installations. Identified by manufacturer part number 1SNA199275R0300, this grey terminal block combines the fast connection benefits of the ADO System with a conventional screw-clamp connection.
As part of the TE Connectivity Entrelec ADO terminal block range, the DR4/6.ADO is particularly suited to applications where installation space is restricted. Its miniature format provides a 6 mm width while allowing conductors to be connected using ADO System technology on one side and standard screw-clamp termination on the other.
The DR4/6.ADO has a 17.5 A IEC rated current and an 800 V IEC rated voltage. The ADO connection accepts flexible conductors from 0.34–1.5 mm², while the compact terminal is designed for mounting on TH15-5.5 DIN rail. It is supplied in grey and has IP20 protection at the main terminals.

Compact ADO and Screw-Clamp Connections for Restricted Spaces
The TE Connectivity DR4/6.ADO combines ADO System technology with a standard screw-clamp connection to provide a compact solution for industrial wiring. The ADO System is designed to provide fast and reliable conductor termination while supporting up to two wires per connection, helping reduce installation time in control panel assembly.
With a 6 mm width and compact 33.5 mm height, the DR4/6.ADO is particularly suited to applications where panel space is restricted. Its IP20 protection, UL94 V0 insulation material and DIN rail mounting make it suitable for organised industrial control and automation installations.
Typical Applications
- Industrial electrical control panels.
- Machine building and industrial automation.
- Process control and instrumentation systems.
- Electrical switchgear and control cabinets.
- Compact DIN rail wiring installations.
- Industrial machine control equipment.
- Applications where restricted panel space requires miniature terminal blocks.
