Webshunt serves as an index mark, and the relay pick-up setting is indicated by the calibration scale marking which is adjacent to the groove. The construction of the plunger, core and flux shunt (which differ in details in the various types of these relays) causes the plunger to float in its energized position, without being held against a stop, even WebThus pick-up current equals the rated secondary current of CT multiplied by current setting. For example suppose that an overcurrent relay having a current setting of 150% is connected to a supply circuit through a CT of 500/5 A. The rated secondary current of CT is 5 A and, therefore, the pick-up value will be 1.5 x 5 i.e., 7.5 A.
