The circuit breaker is used for the following functions:
• Line protection
• Generator protection
• Motor protection
• High breaking capacity
– 3WL10 air circuit breakers: Up to 66 kA
– 3VA27 molded case circuit breakers: Up to 110 kA
• Selectivity, in particular, for high coordination requirements based on time, current, and
energy discrimination.
• Communication
• As a version of a non-automatic air circuit breaker in accordance with IEC 60947-3
For this purpose, the focus is on the following applications of the circuit breaker:
• Main distribution board
• Industrial distribution systems
• Distribution for infrastructure applications (e.g. secondary substations)
• Applications in machine construction
