Grid resistors model RAG

The GRF Grid Type Resistor Groups may be supplied assembled in packs and connected serially or in parallel (depending on the final ohm value), mounted and fixed inside a galvanised steel case with an open bottom and lateral slots for cooling.
The high quality of the materials used to produce this type of resistor makes it particularly suited in the case of high current and low resistance values; in fact, these resistors are used in the start up and adjustment of large motors, in electrical braking (lifting) and in loading systems for generating sets, test benches, harmonics suppressors and grounding of the star centre. The conformation of the grid permits great flexibility in adding additional intermediate fixed sockets.
