* Reliable and simple planning of power distribution by type-tested connection to SIVACON switchboard and transformers
* High water protection (sprinkler suitable)
* Many fields of application thanks to compact design in two sizes from 1,100 A to 5,000 A
* High availability through tap-off units with circuit breakers up to 1,250 A

Reliable Power Transportation for High Power Requirements

The LD system offering rapid and safe mounting covers the current range from 1,100 A to 5,000 A. It transports and distributes the power between the transformer, main power distribution board and sub-distribution boards on production sites with high power requirements, e.g. for welding lines in the automotive industry.
