1SNA199108R0500 – D4/6.SN.ADO disconnect terminal

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

The TE Connectivity D4/6.SN.ADO is a compact knife disconnect terminal block designed for reliable electrical connections, testing and circuit isolation in industrial control panels, automation systems and instrumentation applications. Identified by manufacturer part number 1SNA199108R0500, this orange terminal combines an ADO System connection with screw-clamp technology and a manually operated disconnect blade.

As part of the TE Connectivity Entrelec SNA ADO terminal block range, the D4/6.SN.ADO provides a convenient means of disconnecting circuits for testing and maintenance. The terminal incorporates a 2 mm test socket on the ADO side, while the ADO System allows fast and reliable conductor termination with up to two wires per connection.

The D4/6.SN.ADO has a 6 mm width, a 10 A rated current and a 500 V rated voltage. It accepts 0.34–1.5 mm² conductors through the ADO connection and 0.2–4 mm² rigid conductors through the screw-clamp connection, making it suitable for compact industrial control and instrumentation installations.
