The mass of a sealed enclosure with a dial diameter 260 mm — 4.5 kg. it is Mounted on a vertical sheet into the hole of the corresponding diameter. Usually such an installation place is provided on the body of the dilator of the transformer. The length of the operating lever of the float may be different depending on the capacity and size of the transformer.

In the delivery set includes the device, the drive lever, cable clutch for wires and float. Connecting the electrical contacts of the reed switches manufactured according to the diagram of the protective circuit of the transformer. Each device has a technical passport.
