Descrizione del prodotto

The current asymmetry relay IP 9278 or SP 9278CT monitors the current symmetry of the 3 phases in three-phase networks. With the integrated current transformers, currents of up to 100 A can be measured. In the event of asymmetry, the changeover relay is switched after the adjustable delay time tv has elapsed. Optionally, the error can be stored.
