High Current Disconnectors
HDS high-current disconnectors

The indoor disconnectors offered by HOLDUCT Sp. o.o. are dedicated for currents in excess of 5000A and for high-performance circuit breaker systems. They are characterized by a telescopic structure and a frame made of non-magnetic materials.

The high-current disconnectors use the technology of multiple terminal points, resulting in a very low connection resistance.

The high-current disconnectors range includes:

  • three-phase telescopic disconnectors for currents above 5kA,
  • single-phase, telescopic disconnectors to be used inside busways (power evacuation systems).


In addition to our standard high-current disconnectors, we also produce custom-designed disconnectors to our clients’ specifications. These include: jumpers for transformer measurements based on the telescopic disconnector technology, making it possible to measure the transformers without busducts disconnection.
