POWER CONSUMPTION REDUCING UNIT IN STARTING RELAY FOR MOTOR

摘要

PURPOSE: To obtain a power consumption reducing unit in starting relay for motor which can be applied easily to an existing apparatus while enhancing the reliability. CONSTITUTION: A power reduction relay 21, comprising an auxiliary resistive element 12 having positive temperature coefficient of resistance and a bidirectional three terminal thyristor 11, is connected in series with a starting relay 1 and the power reduction relay 21 is disposed while being spaced apart from a single phase induction motor 2.
