SIA-B & SIA-C PRINCIPAL APPLICATIONS

In Renewable energies, the relays are very compact so they are very useful because the switchgear in this application is really small.

In photovoltaic installations the idea of Fanox solutions is the Standard SIA-B. Why? Because in this market it is really important to use a really competitive and easy relay.

In the case of wind-powered we usually use the Standard SIA-B. We can find this relay in two applications, it can work as a mind protection of the installation or it can work as a backup protection. If the mind protection loses the power supplier we will have the self-powered relay to protect again short circuit and earth fault.
