Fronius > Rapid Shutdown Box-Quattro for Galvo / Primo Interters, Dual / Multi DC String, 25A Max Per Input
Includes mounting Bracket
The new generation Fronius Rapid Shutdown Box 4,240,154 (RSB) provides a convenient solution for NEC 2014 (690.12) and
NEC 2017 (Array Disconnect) compliance, while enhancing overall rooftop and firefighter safety. Low-profile design,
installer-friendly mounting and wiring, make the Fronius Rapid Shutdown Box the ultimate solution for all Fronius
SnapINverters* in systems up to 600 V. 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.
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. 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.
