Continuity in infrastructures
The main reason to equip infrastructures with the REC4 circuit breaker is to maximise single-phase load service continuity. The device will reclose almost instantly as long as there is no permanent leakage, avoiding shutdowns in different systems that lead to substantial economic losses which must be avoided at all costs.
Wherever equipment is operating autonomously from a remote location, Circutor's self-reclosing RCCB will safely reclose in the event of protections tripping.
In the event of transient leakage tripping, the system will ensure that the installation continues to operate normally. On the other hand, if permanent leakage is really occurring, the system will try to reclose up to three times and if it the leakage persists, reclosing will not be completed, leaving the circuit open for a specialist to inspect it.
For example, in the telecommunications industry it is very common to have different antennas spread over the country, with some of them located far away or inaccessible. A downtime in this type of infrastructure could lead to losses of around €30,000/min for the company, in addition to the cost and inconvenience of displacing personnel to the site to simply flip the switch.
Other examples along these lines would be public lighting installations, guaranteeing that the lighting system works in the city or on the roads, or the reclosing of low-cost petrol station facilities that do not have personnel on site to manually carry out reclosing. Instead of moving to locations to restore normal operation, the REC4 would restore the installation's proper functioning.
As regards the services sector, having the self-reclosing RCCB would be an important asset in systems like lighting, air-conditioning, surveillance camera networks or uninterruptible power supplies (UPS) to keep them working at all times, both in small establishments and large stores or shopping centres.
