Fronius Rapid Shutdown Box Duo
The Fronius Rapid Shutdown Box Duo solution has been specially developed for the demands of the North American market and is a reliable, easy-to-install solution for quickly disabling PV generators. Compliant with NEC 2014 (690.12) and NEC 2017 (Array Disconnect), the rapid shutdown box is suitable for all North American SnapINverters up to a maximum system voltage of 600 V.
As the box is connected directly to the inverter and can be mounted conveniently under the module, it needs neither additional components nor a dedicated power supply. These advantages of our solution mean that the installation is simplified and system costs are slashed.
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 our new generation rapid shutdown box even easier.
The Duo rapid shutdown has one input and one output, handling up to 25 Amp DC and 600 Volt. The input side has MC4 connectors, and by using a Y-connector this can be made to handle 2 input strings (combined into 1 output string).
