Why Choose the ABB DDA204 AC-40/0.03 AP-R RCD Block?

The ABB DDA204 AC-40/0.03 AP-R is a four-pole Type AC residual current device (RCD) block with ABB's AP-R high-immunity characteristic, designed for assembly with compatible ABB miniature circuit breakers. Part of the ABB DDA200 RCD block series, it provides residual-current protection for electrical distribution systems while offering enhanced resistance to unwanted tripping.

This Type AC RCD block is designed to detect sinusoidal alternating residual currents. Its 30 mA rated residual operating current provides high-sensitivity residual-current protection, while the AP-R characteristic improves immunity to transient disturbances that can otherwise cause nuisance operation.

With a 40 A rated current and four-pole configuration, the DDA204 AC-40/0.03 AP-R is suited to multi-pole circuits where Type AC residual-current protection and enhanced continuity of service are required. When combined with a compatible ABB miniature circuit breaker, the assembly provides residual-current protection alongside the MCB's overcurrent and short-circuit protection.

Key Advantages

  • Four-pole RCD block for multi-pole electrical circuits.
  • 40 A rated current for compatible ABB circuit protection assemblies.
  • 30 mA rated residual operating current for high-sensitivity protection.
  • Type AC residual-current detection for sinusoidal alternating residual currents.
  • AP-R high-immunity characteristic helps reduce unwanted tripping caused by transient disturbances.
  • Designed for combination with compatible ABB miniature circuit breakers.

Key Features

  • ABB DDA200 RCD block series.
  • Four-pole configuration.
  • 40 A rated current.
  • 30 mA rated residual operating current.
  • Type AC residual-current characteristic.
  • AP-R high-immunity characteristic.
  • Detection of sinusoidal alternating residual currents.
  • 50–60 Hz rated frequency.
  • Modular design for combination with compatible ABB MCBs.

High-Immunity AP-R Residual-Current Protection

Residual current devices monitor the balance of current flowing through the active conductors of an electrical circuit. If an insulation fault or leakage path causes current to flow to earth, the resulting imbalance can initiate disconnection when the RCD block is correctly combined with its compatible circuit breaker.

The AP-R characteristic is designed to provide increased immunity to transient disturbances compared with standard instantaneous residual-current protection, helping reduce unwanted tripping and improve continuity of service. Combined with 30 mA Type AC protection, the DDA204 AC-40/0.03 AP-R is intended for circuits where sinusoidal AC residual-current detection and enhanced immunity are required.

Typical Applications

  • Residential electrical distribution boards.
  • Commercial building electrical installations.
  • Industrial distribution and control panels.
  • Four-pole circuits requiring 30 mA Type AC residual-current protection.
  • Installations where improved immunity to transient-related unwanted tripping is beneficial.
  • ABB modular circuit protection assemblies.
