Click Scolmore continues to expand its Elucian consumer units and protective devices ranges and now offers three different RCBO devices: a 25A RCBO, a compact one pole and switched neutral (Type A) RCBO, and a bidirectional 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.
Which RCBO?
With three different RCBO types available, Click Scolmore provides some insight into each one and their specific uses:
• Standard RCBOs, known as one pole plus unswitched neutral, were the norm. Their uses ranged from socket circuits to lighting circuits across the board and they were found in many typical installations.
• The second iteration of the device was similar to the aforementioned, but included a switch neutral. 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 – 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.
