摘要：A compact circuit breaker containing an electronic trip unit for interruptingovercurrent conditions within a protected circuit is made operable over a wide operatingcurrent range by means of current transformers having multiple turn primary windings.The primary windings are selected to provide a constant ampere-turns ratio to thecurrent transformers without changing the size of the secondary winding or the volumeof the transformer core.
