Fronius 4,240,153 DUO Rapid Shutdown Box, Single/Dual String, 600VDC, 25A, For All 600VDC Inverters 3.8kW-15kW, MC4, 1 String In (2 with Branch Connectors), 1 Circuit Out, With Mounting Bracket
The new generation 4,240,153 DUO Rapid Shutdown Box (RSB) provides a convenient solution for NEC 2014 (690.12) and NEC 2017 (Array Disconnect) compliance, while enhancing overall rooftop and firefighter safety. The low-profile design, installer-friendly mounting and wiring, make the Fronius 4,240,153 DUO Rapid Shutdown Box the ultimate solution for all Fronius SnapINverters in systems up to 600VDC. The box is directly connected to the inverter through the same conduit as the DC homeruns and powered by the array, the Fronius solution minimizes the number of components and eliminates the need for an external power supply. It's low-profile design allows for installation underneath the modules, insuring a clean system look and 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 their new generation Rapid Shutdown Box even easier. Rapid Shutdown is triggered when AC is not present at the inverter, rapidly discharging the DC lines to the inverter. This allows for a seamless, code compliant solution to the NEC requirement for rapid shutdown functionality for PV systems on buildings.
