C Curve RCBOs are designed for circuits with higher inrush currents, such as motors, compressors, machinery, pumps, power tools and certain EV or renewable system components. They provide combined overcurrent and earth-leakage protection in one device, while allowing for short, controlled startup surges without nuisance tripping.
These RCBOs operate within the C-curve tripping band, giving them tolerance for initial current spikes of five to ten times the rated current. They are commonly used in properties with high-load appliances, workshops, small commercial settings and inverter-driven equipment. Most models include switched neutrals, compact modules and Type A sensitivity for modern loads.
Installers choose C Curve RCBOs for circuits that need robust overcurrent protection without unnecessary disconnections during appliance startup. All ratings, dimensions and characteristics are detailed within each individual product listing.

A C curve RCBO provides overcurrent, short-circuit and earth-leakage protection while accommodating higher initial current spikes. These devices trip between five and ten times their rated current, making them suitable for circuits with motors, compressors and load-heavy equipment.
C curve devices are engineered to avoid nuisance tripping on equipment that naturally draws higher current at startup. They still provide rapid disconnect under genuine fault conditions, ensuring safe operation while supporting demanding loads.
All C Curve RCBOs in this category comply with BS 7671 (18th Edition) and meet the performance and safety requirements of IEC/EN 61009. They are suitable for use in consumer units and distribution boards where higher load tolerance is required.
These RCBOs are available from 6A through to 50A, covering everything from small circuits to heavy appliance feeds. Choosing the correct rating depends on cable size, load characteristics and the installation environment. Matching both the rating and the curve to the equipment prevents nuisance tripping and ensures long-term circuit stability.
C Curve RCBOs offer enhanced surge tolerance, cleaner separation of circuits and reliable fault protection. Their compact design, switched neutrals and strong operating characteristics make them a dependable choice for both domestic and commercial setups requiring higher load handling.
