FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Electromagnetic drive has yoke (9) for guiding magnetic flux and holding plate (6) attached to actuating member (1). Holding plate (6) and yoke (9) form a first magnetic circuit. Device for generation of magnetic flux provides enables generation of magnetic flux in first magnetic circuit. Device for generation of magnetic flux comprises under voltage release coil (5) electrically connected to an auxiliary voltage source with value of monitored voltage.
EFFECT: technical result is improved reliability by eliminating need for protection against undervoltage.
