Fronius RSD-DUO Rapid Shutdown Box

Fronius DUO Rapid Shutdown Box for NEC 690.12 Compliance
Fronius USA is proud to offer a bankable solution to the latest National Electrical Code (NEC) requirements of Rapid Shutdown function (NEC 690.12) on rooftop photovoltaic systems. The Fronius Rapid Shutdown Box ensures NEC 2014 code compliance while enhancing rooftop and firefighter safety, quality, reliability and the most seamless solution on the market.
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 severe 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.
Compatible inverters: Fronius Galvo, Fronius Primo, Fronius Symo (excluding the Fronius Symo 15.0-3 208) up to 600V
