NC monitoring relays | Choosing the Right Protection Relay
Protection relays enable the safe distribution of electricity from the grid. Their function is to detect anomalies in the grid that could lead to dangerous situations and, if necessary, interrupt the electrical circuit for as long as necessary. They provide differential, overcurrent, and arc flash protection. This protection is ensured by the relay’s ability to respond rapidly. A relay can consist of several modules, each with its own function.
