Hager RCD 80A Type A 30mA 2 Pole 2 Module CDA283U

Hager CD283U: 80A 30mA 2 Pole RCCB Type A, a DIN rail residual current circuit breaker built for automatic earth fault disconnection on line and neutral circuits.

Reliable Earth Fault Protection

This residual current circuit breaker (RCCB) opens the circuit automatically the moment it detects an earth fault between line and earth, or neutral and earth. That means faster disconnection when a fault occurs, reducing the risk of electric shock and fire on the installation.

Clear Status Indication for Faster Diagnostics

A rectangular flag indicator shows contact position at a glance: red for closed, green for open. A separate yellow flag confirms when the device has tripped, so electricians can identify a faulted circuit quickly without guesswork during fault-finding or routine testing.

Installer-Friendly Design & Compliance

Built to BS EN 61008 and IEC1008, this Hager RCCB fits standard DIN rail enclosures and takes up just 2 module widths, keeping consumer units compact. The trip-free mechanism can be padlocked on or off using a Hager MZN175 accessory, giving contractors a secure way to isolate circuits during maintenance. As part of Hager Ltd's wider circuit protection range, which also includes AFDD arc fault detection devices, this RCCB slots straight into existing Hager distribution boards.

Robust Terminal Capacity for Heavier Loads

Rated at 80A, this 2 pole RCCB accepts rigid conductors up to 50mm² and flexible conductors up to 35mm², making it suitable for higher-current sub-main and distribution applications where smaller RCCBs fall short.
