MCCB Current Setting | I2t | Ir | Isd | Ii | Ig Explanation
I = Short-circuit current (A r.m.s.) k = Insulated conductor constant (which can be calculate using this) Instantaneous current setting (Ii): It is denoted by Ii. Subordinate i means instantaneous. Instantaneous fault means the current goes high in very short period. To protect the circuit against such fault these instantaneous protection is used.
