The Fronius Rapid Shutdown Box (RSB) offers an efficient way to meet NEC 2014 (690.12) requirements while boosting rooftop and firefighter safety. Its compact, low-profile design and easy mounting simplify installation for all Fronius SnapINverters* in systems up to 600 V. Connecting directly to the inverter via the same conduit as the DC homeruns and powered by the solar array, it reduces components and removes the need for an external power supply or control button. Designed for harsh outdoor conditions with a NEMA 4X rating, it fits neatly under modules for a sleek appearance. Wiring is straightforward with MC4 connectors, spring-loaded terminals, and ample space. Rapid Shutdown activates when AC power is lost, quickly discharging DC lines, with an optional emergency stop button for added control.
