In the realm of electrical distribution and automation, the DDA200AC category represents a specialized line of residual current circuit breakers (RCCBs) designed for AC systems. These devices, often referred to as earth leakage circuit breakers or ground fault circuit interrupters (GFCIs) in various global markets, are critical for protecting personnel and equipment against earth faults. The DDA200AC series typically features a 2-pole configuration (2P) for single-phase networks, with a rated current range from 25A to 63A and a rated residual operating current (IΔn) of 30mA, 100mA, or 300mA, ensuring sensitivity to leakage currents. They operate at a rated voltage of 230V AC, 50/60Hz, and are designed for modular DIN rail mounting, making them ideal for integration into standard distribution boards. The electromechanical design ensures high reliability without the need for auxiliary power, and they often include a test button for periodic verification of functionality.
These RCCBs are primarily deployed in residential, commercial, and light industrial installations where protection against indirect contact and fire hazards due to earth faults is mandatory. Common applications include main distribution boards (MDBs), sub-distribution boards (SDBs), and final circuits in buildings, such as lighting, socket outlets, and HVAC systems. They are also used in automation panels for machinery protection, ensuring compliance with IEC 61008-1 standards. The DDA200AC series is particularly suited for environments with high leakage currents, such as those with electronic equipment, providing selective coordination when used with upstream devices.
The DDA200AC category encompasses several subcategories and key article codes, including the DDA200 AC 25A 30mA, DDA200 AC 40A 100mA, and DDA200 AC 63A 300mA variants. These codes typically follow a naming convention: 'DDA200' indicates the series, followed by the rated current (e.g., '25A') and the residual current sensitivity (e.g., '30mA'). Additional variants may include the DDA200 AC 40A 30mA and DDA200 AC 63A 30mA for standard protection, or the DDA200 AC 25A 100mA for fire protection applications. Each unit is designed for quick installation with a 1-module width (18mm) per pole, and they are compatible with busbar systems for efficient wiring.
