Description

ABB Residual Current Device (RCD) DDA 200 series F y type – Direct Pulsating Current Protection | S 200 MCB Assembly

The ABB DDA 200 Series F Type Residual Current Block is a professional-grade component that creates a customizable and effective earth leakage protection system when assembled with ABB’s S 200 series Miniature Circuit Breakers.

Key Protection Features and Suitability:

• Fy-Type Fault Protection: The Fy Type device is engineered to protect against both standard sinusoidal alternating and the more complex direct pulsating earth fault currents.
• Inverter Compatibility: It is specifically suitable for safeguarding lines that supply single phase inverters, a common requirement in modern solar and UPS installations.
• Personnel Safety: It provides protection against indirect contacts, and when the 30mA residual current option is used, it offers additional protection against direct contacts.

This DDA 200 series safety block is available in a 2-pole configuration (DDA 202 F) with rated currents of 40A and 63A at 30mA sensitivity. It is fully compliant with the IEC/EN 61009-1 Ann. G standard, ensuring certified safety across all applications.
