Reliable Protective-Earth Connections with ADO System
The ADO System is designed to provide reliable electrical connections while simplifying installation within modular terminal block systems. The D6/8.P.ADO3 combines a screw clamp connection for the conductor with a screwless rail contact, providing a dedicated grounding solution for industrial control panels and electrical installations.
The terminal block mounts directly onto standard DIN rails and uses a green-yellow body for straightforward identification of the protective-earth circuit. Its robust polyamide insulation and UL94 V-0 flammability rating make it suitable for demanding industrial panel-building environments.
Typical Applications
- Protective-earth connections in industrial control panels.
- Electrical distribution and automation cabinets.
- Machine control panels and industrial machinery.
- DIN rail-mounted grounding systems.
- Industrial automation and process control installations.
- Panel building and electrical assembly applications.
