Hager RCCB Type A 100A 30mA Single Pole & Neutral CDA584U

Hager CDA584U: 100A 30mA Type A RCCB (1P+N) for single-phase installations requiring protection against AC and pulsating DC residual currents.

Reliable Fault Protection

Type A residual current detection identifies both standard AC earth faults and pulsating DC faults, a common requirement on circuits feeding electronic loads such as variable speed drives, LED lighting, or EV charging equipment. The 30mA trip sensitivity meets the threshold required for protection against electric shock, reducing risk to personnel on the circuits it protects.

A breaking capacity (Idm) of 1.25kA and rated conditional short-circuit current (Inc) of 10kA, when correctly backed up by an upstream MCB or fuse, gives the device the robustness needed to withstand fault conditions without failure. An integrated test button lets installers and end users verify correct operation at routine service intervals.

Space-Saving Installation & Compliance

At just 36mm wide (2 modules), the CDA584U fits easily into distribution boards and consumer units where panel space is at a premium. Screw terminals accept conductors from 1mm² up to 50mm² (solid) or 35mm² (flexible), with a specified 3.6Nm tightening torque on both top and bottom terminals for a secure, code-compliant termination. The biconnect bottom terminal simplifies cross-connection on multi-way installations.

IP20 ingress protection and DIN rail mounting support fast, standard installation practice, while the 230V AC rating at 50Hz covers typical single-phase UK supply conditions.

Built for Durability

Rated for 10,000 electrical operating cycles and 20,000 mechanical operations, the CDA584U is specified for long service life in demanding environments. An operating temperature range of -25°C to +50°C and altitude rating to 2000m extend its suitability to a wide range of installation locations, from unheated outbuildings to standard domestic and light commercial settings.
