Abstract

The invention relates to an electromagnetic operating device intended for medium-voltage and high-voltage circuit breakers. The operating device comprises an opening magnet (11) and a closing magnet (15), each of which comprises an operating coil (12, 16), a magnetic core (13, 17) and an armature (14, 18) to operate the movable contact system of the circuit breaker. The two magnetic cores (13, 17) are integrated into one single magnet body (20). The oeperating coils (12, 16) are connected to a common energy source (30) via separate semiconductor switches (31, 32). By energizing the respective operating coil (12, 16), the two armatures (14, 18) are translatorily displaceable along the longitudinal axis of the magnet body (20) for, respectively, opening and closing of the circuit breaker.
