Discover the advantages of Fanox Self-powered Protection Relays

The SIA Range Protection Relays are the right solution for the protection of Secondary Transformers and Distribution Substations in Electrical Networks.

These relays are self powered by the operating current and they provide a complete overcurrent and earth fault protection. The advantage is that they don’t use batteries, chargers or any other external power sources. This means that the maintenance of distribution centers is heavily reduced, thus providing the most cost-effective and reliable solution for the lifecycle of the distribution networks.
