Description
WRB125C-030 is a 25A C Curve high immunity Type A mini RCBO designed for circuits with higher inrush characteristics. It combines overload, short-circuit, and residual current protection in one compact device, making it suitable for domestic and commercial installations where board space is limited.
As part of the Whitecliffe WRB range, this RCBO provides Type A residual current protection, detecting both AC and pulsating DC components. Its high immunity design helps reduce nuisance tripping, while the bi-directional format makes it suitable for modern electrical systems including inverter-led applications.
Installer Tip: A 25A C Curve RCBO is useful on circuits with higher startup demand, where a B Curve device may trip too readily during energisation.
Key Features
- 25A rated current – suited to medium-load circuits
- C Curve tripping – better suited to higher inrush applications
- Type A protection – detects AC and pulsating DC components
- High immunity design – helps reduce nuisance tripping
- 30mA residual current protection
- 6kA breaking capacity
- 1P+N format – single pole with switched neutral
- Compact 18mm width – saves valuable board space
- Bi-directional operation – suitable for modern installation layouts

- Ensure correct line and neutral termination before energising
- Test protective operation during commissioning
- Allow for the compact 18mm single-module width in board planning
FAQs
What circuits is WRB125C-030 best suited to?
It is suited to circuits with higher startup or inrush characteristics where a C Curve device is preferred over a B Curve alternative.
What does Type A protection mean?
Type A protection means the RCBO can detect AC and pulsating DC residual current components.
What is the benefit of high immunity?
High immunity helps reduce nuisance tripping caused by electrical disturbances, making the device more stable on demanding circuits.
Does WRB125C-030 switch both conductors?
It is a 1P+N device with switched neutral, providing isolation of the neutral alongside the live pole.
What is the size of this RCBO?
The device has a compact single-module width of 18mm, with overall dimensions of 18 x 90 x 77mm.
