MULTIPOLE ELECTROMAGNETIC SWITCHING MODULE Russian patent published in 2003 - IPC

FIELD: electrical engineering. SUBSTANCE: multipole switching module connected through power supply terminals to main multipole electromagnetic switching unit and through load terminals, to at least one electric motor has several current lines between these terminals provided with switching poles and alternately closed contacts actuated by switching electromagnet controlled by electric control circuit. Poles and current lines of this module are made so that they enable implementation of motor control function of current reversal or starting with star-to-delta change- over, or distribution function; pole drive system formed by switching electromagnet and electric control circuit is offset relative to switching poles and current lines in direction perpendicular to rear surface of module fixation so as to reduce module width and actually to make it equal to that of associated main switching unit. EFFECT: reduced width of module, enhanced safety of main switching unit. 16 cl, 10 dwg
