Click Scolmore continues to develop its growing range of Elucian consumer units and protective devices and the latest addition is a new bidirectional RCBO.
The launch comes hot on the heels of Amendment 3 of BS 7671 (BS 7671: 2018+A3:2024), which followed the issue of a technical bulletin by BEAMA in 2024 which detailed a concern where, under certain circumstances, protective devices failed to safely operate when required where current flowed in either direction.
Issued on 31st July 2024 for immediate implementation, Amendment 3 introduces one new requirement (Regulation 530.3.201) and two new definitions.
Regulation 530.3.201 requires that due account is taken by the designer and installer of the likely direction of current flow and select protective equipment accordingly. The two new definitions are:
The Elucian Bidirectional RCBO is crucial for ensuring user protection in the event of a fault during a loss of supply. These devices are commonly used with generating sets, where the current can flow in both directions, ensuring that the installer is still protected under fault conditions.
As per the BEAMA guidance when selecting your protective device please ensure that the markings on the device are in line with the guidance. This will ensure compliance with the above regulations.
The new bidirectional RCBO is Type A rated and available in both B curve and C curve, with 6A, 10A, 16A, 20A, 25A, 32A, 40A and 45A options. It comes with a three year warranty.
