Application examples
6.1 Example 1
3-phase circuit breaker with single
interrupter per phase and common
operating mechanism
How to connect
Test quantities
▪ Main contact timing measured by the Timing M/R section
▪ Auxiliary contact timing (one a & one b contact) measured
by the Control section

Calculation points
Whenever possible do settings according to manufac-
turers definition. However if that is not available you
can make your own choice and use it as your own
reference.
