In relay terminology, the 'pickup value' refers to the minimum value of the input quantity (like current or voltage) at which the relay starts to operate or activate. It is the threshold beyond which the relay detects a fault and initiates a response.
Calculation
If the operating quantity (such as current or voltage) exceeds the pickup value, the relay coil gets energized and the relay contacts begin to move to their operating positions. This threshold ensures the relay doesn't operate for minor fluctuations.
Other options describe time delay, reset value, or withstand capacity, which are different from the pickup function.
