  • Easy voltage fitting, thanks to optional retrofittable terminal blocks
  • Easy potential distribution, thanks to screw or insertion bridges
  • Continuous marking and test options
  • Flexible mounting, thanks to DIN rail or direct mounting versions
  • Reduced mounting and logistics costs, thanks to pre-assembled terminal block bases

High current potential distributor

Easy potential distribution  

Easy potential distribution

With a 1500 V nominal voltage, the compact UKH 70/4X10 high-current terminal blocks are ideally suited for use in regenerative energy generation – specifically in photovoltaics. Four integrated pick-off terminal blocks with a 10 mm² cross section provide you with a simple power supply or potential distribution. Potential distributor blocks are implemented with screw bridges.
