The CIBANO 500 circuit breaker test system combines a micro-ohmmeter, timing analyzer, and a coil and motor supply in a single device. This enables all important circuit breaker tests to be carried out even when a station battery is not available.

With the 3-in-1 system all types of circuit breakers (medium- and high-voltage circuit breakers with live and dead tank design) can be tested. It features a globally unique connection technology which considerably reduces the wiring effort and time required. In addition, OMICRON’s Primary Test Manager Software (PTM) ensures convenient operation and delivers one clear, combined report for all the tests performed.

The innovative accessories can be used to extend the scope of testing as well as increase convenience and safety during testing.


The following 5 standard tests can be carried out on all circuit breakers using CIBANO 500:

  • Static contact resistance test (micro-ohm measurement)
  • Timing tests
  • Coil and motor current analysis
  • Minimum pick-up test
  • Under-voltage condition test
