OTDC 100…250A (IEC and UL)

Simply optimal

OTDC switch-disconnectors from 100A up to 250A ensure reliable breaking power for all current levels, without compromising safety, efficiency and simplicity.
The basic configuration is two poles for 1000V DC, from 100A up to 250A (IEC 60947) and from 100 to 250A (UL98B). Side operated versions are available from 100 to 250A (UL). The basic configuration for 1500V DC is four poles, from 100A up to 250A (IEC 60947) and from 100 to 200A (UL98B).
