Hager ADC 1 Module Single Pole Type A RCBO C-40A 10kA 30mA – Reliable Circuit Protection for High-Inrush Applications
The Hager ADC 1 Module Single Pole Type A RCBO is designed for comprehensive circuit protection, combining MCB overcurrent protection with RCD earth fault detection in a compact 1-module design. With a Type C tripping curve, a high breaking capacity of 10kA, and Type A residual current protection, this RCBO is ideal for circuits with moderate inrush currents, such as lighting and motor loads.
- Type A RCBO Functionality – Detects both AC and pulsating DC earth faults, ensuring enhanced safety.
- Type C Tripping Characteristics – Trips between 5 to 10 times full load current, making it suitable for circuits with moderate inrush currents.
- High Breaking Capacity – Rated at 10kA, providing strong short-circuit protection.
- Neutral Position – Right – Designed for efficient and organised wiring.
- Single Pole Design – Ensures safe disconnection and isolation of live conductors.
- DIN Rail Mounting – Compatible with Hager consumer units and distribution boards for easy installation.
