The FT64 are very reliable, high quality air-insulated pole mounted disconnectors. They are available with rated voltages from 12 to 36kV and rated currents 400 or 630A suitable for vertical installation.

The base frames are welded from sectional steel. The operating shafts are made of bronze and are hot-dip galvanized. All insulators used for construction are made of cycloaliphatic epoxy resin all others are made of epoxy resin (colour brown, RAL 8017). The double disconnecting blades are made of silver-plated electrolytic copper and form a loopless current path.

The FT64 is available in following versions:

- FT 6400 - disconnector without fuse holder
- FT 6410 - disconnector with fuse holder

The FT64 can be delivered with an integrated earthing switch or with spark quenching horns suitable for disconnecting low currents.

The disconnectors comply with the specifications of VDE 0670 Part 2 (rated insulation level List 2) and are designed for use under normal operating conditions.
