●

Coil Voltage Reduction (Holding Voltage) after Relay  

operation  

• If the coil voltage is reduced to the holding voltage after Relay  

operation, first apply the rated voltage to the coil for at least  

100 ms, as shown below.  

E

L

• A voltage of at least 50% of the rated voltage is required for  

the coil holding voltage. Do not allow voltage fluctuations to  

cause the coil holding voltage to fall below this level.
