Hager RCCB Type A 80A 30mA Single Pole & Neutral CDA580U

Hager CDA580U: 80A 1P+N RCCB with 30mA Type A residual current protection, designed for reliable circuit protection in domestic and light commercial installations.

Safety & Reliability

Type A residual current detection picks up both AC and pulsating DC fault currents, giving broader protection than standard AC-type devices, useful where modern electronic loads (chargers, LED drivers, inverters) are present on the circuit. A conditional short-circuit rating of 10kA and 1.25kA breaking capacity mean the device withstands fault conditions without compromising the installation. The integrated test button should be pressed every six months to confirm correct tripping, standard practice for any residual current circuit breaker (RCCB) in a maintained installation.

Installation & Compliance

At just 2 modules (36mm) wide, this Hager Ltd circuit protection device fits standard DIN rail enclosures without eating into valuable consumer unit space. Screw terminals rated to 3.60Nm accept conductors from 1mm² up to 50mm² (solid) or 35mm² (flexible), and the biconnect bottom terminal speeds up wiring on site. Rated insulation voltage of 500V and impulse withstand of 4,000V (6,000V to IEC 60947-3) support compliance with EN 61008-1 for 2 residual current circuit breakers (RCCB) installations of this type.

Durability & Performance

Built for long service life, the CDA580U is rated for 10,000 electrical operating cycles and 20,000 mechanical operations. It operates reliably across a wide temperature range of -25°C to +65°C and up to 2,000m altitude, so performance isn't compromised in cold plant rooms, lofts, or exposed switchgear locations. Power dissipation is a modest 10.90W at rated current, limiting heat build-up inside enclosed boards.
