The HAGER CDA440D is a four-pole residual current circuit breaker (RCCB) of type A, designed for rated currents up to 40 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 commercial buildings with three-phase power supply.

Technical Features
  • Article type: Residual current circuit breaker
  • Manufacturer: HAGER
  • Manufacturer type: CDA440D
  • Number of poles: 4-pole
  • Rated current (In): 40 A
  • Rated residual current (IΔn): 30 mA
  • Residual current type: Type A (detects alternating and pulsating direct residual currents)
  • Rated short-circuit current (Inc): 6 kA according to EN 61008-1
  • Breaking capacity (Idm): 1.5 kA
  • Rated operational 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: 40 A
  • Conductor cross-section: 1–25 mm² (solid), 1–16 mm² (flexible)
  • Protection rating: IP20 (when installed)
  • Temperature range: -25 °C to +40 °C
  • Division units: 4
  • Housing material: Halogen-free plastic

Normative Requirements and Obligation to Use
  • DIN VDE 0100-410: Protection against electric shock – Residual current devices ≤ 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 – RCCB 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 CDA440D 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 Protective Function
  • Personal protection: Prevents life-threatening electric shocks through 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 fast disconnection operates independently of the network type (TN, TT, IT) and is especially essential in TT systems, where protection by overcurrent 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.
