Why Choose the TE Connectivity DS4/8.ADO 1SNA299493R2300 Terminal Block?
The TE Connectivity DS4/8.ADO 1SNA299493R2300 is a compact ADO System and screw-clamp feed-through terminal block designed for reliable conductor connections in industrial control panels, machinery and automation systems. Part of the established TE Connectivity / Entrelec SNA ADO terminal block range, it combines the speed and reliability of ADO connection technology with a conventional screw-clamp connection in a space-saving miniblock format.
The DS4/8.ADO allows installers to benefit from the ADO System while retaining the flexibility of a standard screw-clamp termination. The ADO connection provides a fast, secure connection for suitable conductors, while the screw side accommodates both rigid and flexible wiring. This hybrid arrangement makes the terminal particularly useful for control-panel applications requiring dependable connections and flexible installation methods.
With a rated cross-section of 2.5 mm², rated current of 24 A and rated voltage of 1,000 V, the 1SNA299493R2300 provides dependable connectivity for industrial power and control circuits. Its compact 8 mm spacing, grey polyamide housing and DIN rail mounting make it suitable for organised, high-density electrical assemblies.
