Circuit Breaker Servicing

With proper maintenance, industrial circuit breakers can last for decades. Crown ERAM’s technicians thoroughly inspect your switchgear with all applicable tests including:

  • Visual inspection
  • Electrical and mechanical operation
  • Megger® insulation resistance testing
  • Doble® insulation and discharge testing
  • Micro-ohmmeter (contact resistance)
  • Hi-Potential test
  • Vacuum bottle integrity test
  • High current injection of over-current devices
  • Time testing/motion testing

We disassemble the breaker, clean components, and replace worn parts.  The breaker is then reassembled and re-tested. Our machine shop fabricates replacement parts if necessary.
