Fronius Rapid Shutdown Box - 4,240,151

Fronius, Rapid Shutdown Box, Single String, for all single phase inverters 1.5 kw to 8.2 kw, 2 ports for 3/4" conduit, 12.5A, 600VDC, No DC Disconnect switch, includes mounting Bracket, 4,240,151

The Fronius Rapid Shutdown Box provides the ultimate NEC 2014 code (690.12) compliant solution while enhancing rooftop and firefighter safety. With the Fronius Rapid Shutdown Box, Fronius offers a reliable and easy to install solution for all Fronius SnapINverters in systems up to 600 V.

Directly connected to the inverter through the same conduit as the DC homeruns, the Fronius solution minimizes the number of components needed providing ease of installation. No additional power supply is needed, reducing overall system cost and streamlining installation. Rapid Shutdown is triggered whenever AC is not present and the inverter rapidly discharges the DC lines, allowing for a seamless code compliant solution to the 2014 NEC requirement for rapid shutdown functionality for PV systems on buildings.


  • Rated NEMA 4X - Built for severe outdoor conditions. Robust metal housing. Rated for rooftop installation.
  • Mounting - Mounting bracket included. Can be mounted, per NEC 2014, on the roof or racking within 10 feet from the array or in the attic 5 feet within the array.
  • Terminals - Input and output terminals are spring loaded for fast and easy connection without special tools.
