The pick-up current is the level of current that causes the relay plunger to rise and
close the contacts that connect the start winding to the circuit. As the motor speed
rises, the main winding current falls off to a level where the weight of gravity ...

Embedded Hardware: Know It All: Know It All
The case of a pilot relay driving a contactor is a classic case. Contactors (and
relays) have a pick-up current and a hold current. The pick-up current is the
amount of current required to develop a sufficient magnetic field to actuate the
contactor.

Pick-up current. It is the minimum current in the relay coil at which the relay starts
to operate. So long as the current in the relay is less than the pick-up value, the
relay does not operate and the breaker control led by it remains in the closed ...

Here the start-up current is constantly being drawn from the input power line,
even during steady- state operation. If the start-up current is less than the current
required to operate the IC and driver (~0.5mA), then the power supply has a
hiccup ...
