Why Choose the TE Connectivity DR4/8.P.ADO 1SNA299632R0500 Terminal Block?
The TE Connectivity DR4/8.P.ADO 1SNA299632R0500 is a compact green/yellow protective-earth terminal block combining ADO System and screw-clamp connection technology. Part of the established TE Connectivity / Entrelec SNA ADO series, it is designed to provide dependable protective-earth conductor termination in industrial control panels, machinery and automation systems where installation space is limited.
The DR4/8.P.ADO combines the benefits of the Entrelec ADO connection system with a conventional screw clamp, providing flexibility when terminating industrial conductors. Its protective-earth function incorporates a rail connection for grounding through the mounting rail, while the screwless rail contact helps provide a consistent connection that is not dependent on operator-applied rail-contact torque.
With a rated cross-section of 2.5 mm², an 8 mm width and conductor capacity up to 4 mm² on the screw-clamp side, the 1SNA299632R0500 provides a compact grounding solution for industrial electrical installations. Its green/yellow polyamide housing provides immediate protective-earth identification, while an operating temperature range of -55 to +110 °C supports use in demanding environments.

Reliable Protective-Earth Connections for Industrial Panels
Protective-earth terminal blocks provide a dedicated connection between equipment conductors and the grounding system of an electrical installation. The DR4/8.P.ADO uses a screwless rail contact to establish the protective-earth connection through its compatible mounting rail, helping provide consistent grounding without relying on an operator-adjusted rail-contact connection.
The combination of ADO and screw-clamp technology provides flexibility when wiring industrial equipment. The ADO System supports fast conductor termination, while the conventional screw-clamp side accommodates a broad conductor range, making the DR4/8.P.ADO particularly useful for panel builders, machine manufacturers and automation engineers working with compact grounding assemblies.
Typical Applications
- Protective-earth connections in industrial control panels.
- Machine building and OEM automation systems.
- PLC and industrial control cabinets.
- Equipment grounding and protective conductor termination.
- Manufacturing and process automation equipment.
- Compact industrial terminal block assemblies.
