Hager RCD 63A Type A 30mA 2 Pole 2 Module CDA263U

Hager CDA263U: 63A 30mA 2 Pole RCCB Type A, a residual current circuit breaker designed to disconnect automatically in the event of an earth fault between line and earth or neutral and earth.

Safety & Reliability

As a Type A residual current circuit breaker (RCCB), this device detects both AC and pulsating DC earth leakage currents, giving broader protection than a standard AC-type unit. The trip-free mechanism ensures the breaker cannot be held closed against a fault, so protection is never compromised even under sustained pressure on the operating handle.

Clear Status Indication

A rectangular flag indicator shows red for closed and green for open, so installers and maintenance engineers can confirm switch position at a glance without opening the enclosure. A separate yellow flag indicates when the device has tripped on a fault, speeding up diagnosis on site.

Installation & Compliance

Terminals accept 25mm² rigid or 16mm² flexible conductors at this 63A rating, giving flexibility for a range of cable sizes on domestic and light commercial installations. The unit conforms to BS EN 61008 and IEC1008, supporting compliance sign-off without additional certification checks. DIN rail mounting across 2 modular spacings keeps consumer unit layouts compact.

Lockable for Safe Isolation

The RCCB can be padlocked in either the on or off position using a Hager Ltd MZN175 accessory, supporting safe isolation procedures during maintenance or fault-finding work. This is a straightforward way to prevent unauthorised re-energisation while work is in progress.
