RCBO's
Residual current protection with integrated overload tripping
Rowe Hankins Residual Circuit Breaker Overload products (RCBOs) provide combined residual current detection and circuit protection for AC electrical systems. The units perform two primary functions: measuring AC residual current and tripping the circuit when a fault condition is detected, helping to protect equipment and improve electrical safety.

Key Features
Combined Residual Current Detection and Tripping
Measures AC residual current and trips automatically under fault conditions, providing integrated protection within a single device.
Multiple Pole Configurations
Available in 2-pole (Series 373) and 4-pole (Series 368) versions to suit different installation and system requirements.
Configurable Trip Level and Ratings
MCB ratings available up to 50 A, with residual current trip levels factory set between 5 mA and 300 mA. Trip levels up to 2 A are available on 4-pole units.
Time Delay Trip Options
Fixed or inverse time-delay trip characteristics can be specified, allowing coordination with upstream and downstream protection devices.
Standards-Compliant Variants
5 mA trip level options are available to meet the requirements of the American National Electrical Code (NFPA 70).
Built-In Test Functionality
Integrated test button allows verification of correct operation by injecting a test signal through the current transformer.
