Fronius 4,240,153 Rapid Shutdown Box-Duo

The Fronius Rapid Shutdown Box Duo and Quattro generation has been specially developed for the demands of the North American market and is a reliable, easy-to-install solution for quickly disconnecting the PV array from the inverter. Compliant with NEC 2014 (690.12), the Rapid Shutdown Box is suitable for all North American SnapINverters up to a maximum system voltage of 600V (except Symo 15.0-3 208). As the Box is connected to the inverter via a signal wire and can be mounted conveniently under the module, it needs neither additional components nor a dedicated power supply. The Fronius Rapid Shutdown Box Duo and Quattro are a low cost and simple to install Rapid Shutdown solution for Fronius SnapINverters.

The low-profile design allows for installation underneath the modules, ensuring a clean system look. Thanks to the NEMA 4X rating, the box is built for sever outdoor conditions. MC4 connectors, spring loaded terminals and generous wiring space make wiring easy. Rapid Shutdown is triggered when AC is not present at the inverter, rapidly discharging the DC lines to the inverter. An optional method is to install an emergency stop button to open the signal loop.
