Fandis proposes a variety of heaters for the thermo-regulation of electrical cabinets, for application on DIN rail and connectable by bipolar/three-pole cable or by three-pole terminal block. The heater consists of a self-regulating PTC element and black anodized aluminium cover, assuring the maintenance of constant operation by preventing the formation of condensation. The additional use of an integrated 60x60 mm d.c. fan enhances the heating power, up to a thermal capability of 400W.
