HPX high-pressure contact switches

Reliance on step-up transformers to distribute utility-supped 208 Vac power at 480 Vac within high-rise buildings is increasing. With stricter electrical code requirements being enacted, Eaton has developed a HPX high-pressure contact switches that are:

  • Designed to withstand and operate the large inrush currents of step-up transformers and other high-inrush current inductive loads
  • Engineered for simplified replacement of Pringle bolted pressure contact switches in retrofit applications
  • Available with built-in current, voltage, power and energy management
  • UL 977 listed and support UL 891 switchboard applications
