THYRISTOR CONTROL SET WITH OVERCURRENT CIRCUIT-BREAKER

摘要

The invention relates to a thyristor control set for the power supply to and regulation of electrical consumers, especially electric motors, with a switching signal which can be generated by an overcurrent circuit-breaker to control a power switch. The switching signal (ES) of the overcurrent circuit-breaker can be fed to a time-switch device (ZS) shutting off the thyristor, which controls the power switch (LS) with a second, delayed switching signal (WS). Thyristor control sets of this kind are used to supply power to and regulate electrical consumers.
