High Current Switch
General Characteristics
Modular line of Knife Disconnectors suitable to be used at different voltage levels (up to 36kv) in a very wide range of current (up to 6kA per pole).
The independent multiple contacts system with springs in each contact point guarantees a very strong and safe contact with a very low voltage drop and constant performances all over life time.
Epoxy resin Insulators and reinforced fibre glass connecting rods gives to the disconnector a very high level of sturdiness.
Plus
- Very Low contact Resistance
- Low Voltage drop
- High Electrical and Mechanical durability
- Wide modular range
Large customization possible with:
- Actuators (Motor, pneumatic, manual)
- Accessories (limit switches, locks, temperature sensors...)
Safe Operation
