The FT series three-phase capacitors consist of PRT-type three-phase elements, connected in parallel and inserted in a casing made of sturdy sheet steel painted with epoxy resins in the colour RAL 7035.
The special construction features of this casing ensure better dissipation of the heat generated inside it and an improvement in the working conditions of the capacitive units they contain.
The casing is equipped with brackets for fixing to the ground and an outer cover that ensures an IP40 (FT) or IP54 (FTE) protection rating.
Especially suited for fixed power factor correction, such as no load p.f. correction of transformers or fixed p.f. correction of motors.
Installation must be performed using the 8×10 fixing bolts on the brackets at the base of the casing.
For the protection of the FT batteries, it is necessary to connect a protection device upstream the capacitor.
