PV fireman's switch for up to 6 strings

PV fireman's switches are DC switch-disconnectors that isolate the lines between solar modules and inverters. They allow firefighters to operate without the risk of electrocution.

In addition to the SOL30-Safety for small installations Eaton offers prefabricated fireman's switches housing 2, 3, 4 or 6 switch-disconnectors in a common enclosure. In contrast to generator terminal boxes the individual strings are not connected in parallel but can be fed separately to the inverter. This allows the use of several MPP trackers and helps optimise the inverter’s performance.

The fireman's switches are available with metric screw connection or with MC4 sockets.
On the metric devices all cables are connected to the modular terminals, which guarantee a fast and simple installation.
