Why choose it

The ADX475D provides combined protection in a single device, saving space and simplifying wiring. Its Type A residual current detection covers AC and pulsating DC fault currents, making it suitable for circuits with electronic loads.

Ideal use cases

• Protection of three-phase socket outlets and equipment in commercial and industrial installations
• Circuits with electronic ballasts, LED drivers, or single-phase inverters
• Distribution boards where space is limited and individual circuit protection is required

Good to know

Screw terminals accept conductors from 1.5 to 25 mm² rigid and 1.5 to 16 mm² flexible. The device is compliant with EN 61009-1 and rated for 10,000 electrical operations.
