F3R - Outdoor Rated VFD Control Panel
What is the F3R
The F3R is a variable frequency drive control panel manufactured by Motor Drives International. 3R stands for NEMA 3R. This VFD panel is very popular in outdoor applications, such as agriculture, rock crushing, mines, refinery, and more. It is designed for locations that are dusty, sites that may cause it to be hit by small rocks or splashed by water (to an extent). The F3R is a great option to house your VFD and its accessories such as line reactors and bypasses in those environments.
Stock F3R control panels are available in 6 different sizes, housing VFDs ranging from 5HP to 800HP (for higher horse powers, check out MDI's Custom Panels /custom-vfd-panels). Each F3R is equipped with rain hoods, washable poly filters, outdoor-rated panel controls; and is forced air ventilated. Some other features of the F3Rs include an advance numeric keypad, remote I/O capability, and a pad-lockable door handle connected to a circuit breaker disconnect. Optional add-ons include 3% or 5% line reactors, 12% or 15% harmonic filter system, three contactor bypass, and many more.
