The Hager ADC440U is a single-module, single-pole Residual Current Circuit Breaker with Overcurrent Protection (RCBO) rated at 40A with a Type C tripping curve. It is designed to replace older models like the ADA156U and ADC106, offering 10kA breaking capacity and Type A residual current sensitivity to detect both AC and pulsating DC earth faults.
Key Specifications
Current Rating: 40A at 30°C.
Tripping Curve: Type C, which typically trips between 5 to 10 times the full load current, making it suitable for circuits with moderate inrush currents like motors or transformers.
Breaking Capacity: 10kA.
Residual Current Sensitivity: 30mA (Type A).
Dimensions: 115mm (Height) x 17.8mm (Width) x 70mm (Depth).
Neutral Lead: 700mm insulated flying neutral lead for connection to the distribution board.
