The reclosing system guarantees that whenever there is a real fault in the installation, the electricity will be automatically reconnected once the fault clears. The location of this type of facility is often difficult to access, so using this type of solution avoids unnecessary travel to manually reset the service, optimising your time and resources.
Residual current protection can trip with a leakage current well below its rated value, so selecting the right breaker will avoid the costs associated with undesired trips. The regulation specifies that an RCCB can trip with a leakage current more than 50% of its rated current, so if there are cumulative leaks in a line or switchboard, these can cause a service interruption even if the leakage current poses no hazard to the installation.
The best way to solve this problem is to install ultra-immunized RCCBs, since this type of solution contains electronics that guarantee the device will only open if the leakage current is at least 85% of the rated value, meaning it will only trip when the actual leakage current approaches the danger threshold.
Actuating RCCBs remotely through built-in communications makes maintenance more efficient, since lines can be disconnected and connected for only as long as necessary from the control centre, avoiding unnecessary travel.
