The set point current at which a magnetic-type overload relay tends to trip may be increased by turning the dashpot in the 'lower' direction. What effect will this action have? |
A) increases magnetic force on the plunger and requires more current to trip the relay |
B) reduces magnetic force on the plunger and requires more current to trip the relay |
C) increases magnetic force on the plunger and requires less current to trip the relay |
D) reduces magnetic force on the plunger and requires less current to trip the relay |
