Remote operable unipolar/multi polar power circuit breaker for kilowatt-hour meter equipment, has releasing unit, where breaker is directly/indirectly disconnected by power impulse and released by another impulse for resetting of breaker

摘要

The breaker has a remote operable releasing unit with two working positions. The releasing unit actuates a release mechanism of an individual circuit pole until a resetting command takes place for resetting the breaker by hand. The breaker is directly or indirectly disconnected by a power impulse and is released only by another power impulse for resetting the breaker. A command pulse of the breaker operates on the unit.
