The HAGER CDA425D is a four-pole residual current device (RCD) of type A, designed for rated currents up to 25 A and a rated residual current of 30 mA. It meets the requirements of standards EN 61008-1 and IEC 61008-1 and is intended for use in low-voltage installations, especially in residential and utility buildings with three-phase power supply.

Technical Features
  • Article Type: Residual current device
  • Manufacturer: HAGER
  • Manufacturer Type: CDA425D
  • Number of Poles: 4-pole
  • Rated Current (In): 25 A
  • Rated Residual Current (IΔn): 30 mA
  • Residual Current Type: Type A (detects AC and pulsating DC residual currents)
  • Rated Short-Circuit Current (Inc): 6 kA according to EN 61008-1
  • Breaking Capacity (Idm): 1.5 kA
  • Rated Operating Voltage (Ue): 230/400 V AC
  • Insulation Voltage (Ui): 500 V
  • Impulse Withstand Voltage: 4 kV
  • Frequency: 50 Hz
  • Mounting Type: DIN rail mounting
  • Variant: 25 A
  • Conductor Cross-Section: 1–25 mm² (solid), 1–16 mm² (flexible)
  • Protection Rating: IP20 (when installed)
  • Temperature Range: -25 °C to +40 °C
  • Width (Modules): 4
  • Housing Material: Halogen-free plastic

Normative Requirements and Mandatory Use
  • DIN VDE 0100-410: Protection against electric shock – RCDs ≤ 30 mA are mandatory for all socket circuits ≤ 32 A in residential buildings.
  • DIN VDE 0100-530: Selection and erection of electrical equipment – requirements for protective devices.
  • DIN VDE 0100-701: Rooms with bathtubs or showers – RCD protection is compulsory.
  • DIN VDE 0100-722: Electrical installations of charging equipment for electric vehicles – residual current protection with DC detection required (Type A combined with DC monitoring or Type B).
The CDA425D is particularly suitable for Type A applications where no smooth DC residual currents > 6 mA occur. For charging equipment or frequency converters, a Type B or an additional DC residual current sensor may be required.

Safety Aspects and Protection Function
  • Personal Protection: Prevents life-threatening electric shocks from direct or indirect contact.
  • Fire Protection: Detects residual currents caused by insulation faults that can potentially cause fires.
  • System Protection: Prevents damage to electrical equipment by early disconnection in case of residual currents.
The rapid disconnection operates independently of the network type (TN, TT, IT) and is especially essential in TT systems, where protection by overcurrent protective devices alone is insufficient.

Typical Areas of Application
  • Residential Buildings: Protection of socket circuits, lighting circuits, kitchen and bathroom installations.
  • Commercial Use: Protection of office installations, server rooms, workshops.
  • Industry: Use in control cabinets for machines, controls and sub-distributions.
  • Charging Infrastructure (conditional): Suitable in combination with DC residual current monitoring for wallboxes and charging stations.
