Electronic overcurrent protection by means of electronic AC circuit breakers is ideally suited to the selective protection of uninterruptible power supplies (UPS) in industrial plants. These solutions ensure the power safety through AC UPS systems.
Electronic overcurrent protection provided by electronic AC circuit breakers prevents disconnection of th entire output voltage of UPS systems in the event of a short circuit as well as in the event of an overload. At the same time these products ensure selective protection or disconnection even under very unfavourable load conditions. This is achieved by the breakers responding faster than the UPS itself to the overload condition. Besides the selective protection these devices offer a very high entire saving potential.
