Click Scolmore continues to expand its Elucian consumer units and protective devices ranges and now offers three different RCBO devices.
These consist of the following: a 25A RCBO, a compact 1 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, each one has specific uses.
Standard RCBOs, known as 1 pole plus unswitched Neutral, used to be the norm, with uses ranging from socket circuits and lighting circuits across the board. At one point they were found in many typical installations.
The second iteration of the device is similar to the aforementioned, but includes 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.
