Cover Story
Since launch a further 16 products have been developed and added to the range, either to complete the product line up or to provide a solution to a particular installation issue. These include SPD populated units; modular contactors; single module SPDs; unpopulated consumer units, an energy meter (MID approved) and dual row consumer units. Click has also expanded its range of RCBO devices since launch, with the addition of a 25A RCBO, as well as a compact 1 Pole and switched Neutral (Type A) RCBO. The most recent development is the launch of a bidirectional RCBO. This came 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 had the potential to fail and safely operate when required where current flowed in either direction.
Which RCBO?
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.
With three different RCBO types available, Click Scolmore provides some insight into each one and their specific uses: • Standard RCBOs, known as 1 pole plus unswitched Neutral, were the norm, and their uses ranged from socket circuits and lighting circuits across the board and they were found in many typical installations.
• The second iteration of the device was similar to the forementioned but included
a switch neutral, and this version is quickly becoming the new norm for contractors. These devices are typically used where the installation or the piece of equipment it is serving requires the Neutral to be disconnected. For example, Regulation 722.531.3.1 requires RCDs to disconnect all lives.
• The latest device, mentioned above, is the bidirectional RCBO which includes a switched Neutral. These would be used where energy flow is possible in both directions from a generating set and this is outlined in Regulation 530.3.201. Examples of such installations would include, but are not limited to, PV systems, battery storage systems and EV chargers.
