Description

ABB Residual Current Device RCD DDA 800 AC w type for MCBs S800 – Excellent Modular Sinusoidal Earth Fault Protection for S800 MCBs

The ABB RCD DDA 800 AC Residual Current Block provides industrial-grade earth fault protection for critical electrical distribution systems. By attaching directly to the S800 series of MCBs, this modular unit offers a robust, space-saving solution for superior safety.

Key Technical Specifications & Benefits:

• AC Type Functionality: Ensures safety by detecting and interrupting sinusoidal alternating earth fault currents.
• High Voltage Rating: Operates with a rated voltage up to 690V and an insulation voltage of 690V, making it suitable for high-power industrial environments.
• Durability: Engineered for longevity with a mechanical endurance of 20,000 cycles and an electrical endurance of 10,000 cycles.
• Safety Features: Provides protection against indirect contacts, and offers additional protection against direct contacts when using the 30mA residual current option.
• Configurations: Available in 2, 3, and 4-pole versions, with sensitivities (IΔn) of 30mA and 300mA for 63A rated currents.

Compliant with IEC/EN 60947-2 Ann. B, the DDA 800 AC Block is the definitive choice for reliable earth leakage protection in commercial and industrial settings.
