Circuit Breaker Testing

Circuit breaker testing ensures the proper functioning of your circuit breaker in a critical moment such as a breaking fault current. Over time, electrical contact can wear down or get dirty, lubricants of the mechanical parts can get dried, and thus a short circuit in the coils of the circuit breaker can occur. Therefore, medium and high-voltage circuit breaker testing and maintenance should be performed once per year or after a certain number of operation cycles.
