Abstract
The circuit arrangement for connecting a consumer to an alternating voltage source includes a switch actuator (16) connectable in series with the consumer (12) and an electronic circuit (22) associated with the switch actuator and supplied with a direct voltage by means of it. The switch actuator (16) includes a rectifier for supplying the direct voltage to the electronic circuit, a transformer (24) comprising a secondary winding (32) supplying power to the rectifier, a first low inductance primary winding (26) and a second high inductance primary winding (28) and a switching device (36,42) controlled by the electronic circuit (22) to switch between the primary windings. Another switching device (44) is connected in parallel with the first primary winding (26) in order to short-circuit it for a predetermined short-circuit duration as a function of a nominal power consumed by the consumer. The switching device (36,42) can be a relay or a semiconductor component.
