Plug setting calculation
WebbIn our case you can calculate that, Isd = 1.5 Ir. Here you should consider the over current setting Ir value Not a nominal current value of the MCCB (In). because of when increasing in over current, simultaneously, it increases the short circuit current rating also. In our case Isd= 1.5 * 320 A = 500Amps. WebbIf for an IDMT relay with a plug setting of 50% and a CT ration o.
