Description

ABB Residual Current Device (RCD) DDA 200 series AC w type – Excellent Modular Earth Fault Protection for S 200 MCBs Series

The ABB RCD DDA 200 Type AC Residual Current Block is the dependable modular solution for integrating residual current protection with Miniature Circuit Breakers (MCBs).

This device is explicitly designed to detect and interrupt sinusoidal alternating earth fault currents, the most common type of electrical fault.

Key Features for Reliable Protection:

• AC Type Functionality: Guards against sinusoidal alternating earth fault currents.
• Modular Design: Functions as an earth leakage block that is installed directly onto the ABB S 200 series MCBs.
• Versatile Configurations: Available in 2-pole (DDA 202), 3-pole (DDA 203), and 4-pole (DDA 204) versions.
• High Sensitivity Options: The range of residual current sensitivities (IΔn) includes 10mA, 30mA, 100mA, 300mA, 500mA, and 1000mA (1A).

Fully compliant with IEC/EN 61009-1 Ann. G standards, the DDA 200 AC Protection Block is the certified, secure choice for all standard electrical installations.
