Over-current protection is provided by tripping the relay when motor operating current (In) exceeds over-current setting (Is) of EOCR for a period greater than the preset operating time (O-Time).
During a phase loss, the motor winding current may increase by 150% or more. As the motor winding
current increases, the winding temperature may also increase and possibly damage the winding insulation.
The quick trip time on EOCR helps to prevent overcurrent damage to the windings.
