Standard adjusted: 5-50% sensivity: Fixeddelayof2sec Temperature: -10to+60°C Weight 0.4kgs Front protection: IP41 Description KRM72x monitors three phase AC supplies for incorrect phase sequence, phase failure and phase imbalance on systems up to 500V. Asensitivity adjustmenton the top of the unit allowsadjustmentupto50%of the phase to phase voltage. The minimum level isselectedtoavoid any nuisance tripping due to normal variations in voltages. Afactory set delay of approximately two seconds prevents tripping due to transients. The unit is factory setfor50Hzor60Hz. Itisavailableas a50/60Hz variation with associatedlossofsensitivity. The unit meets IEC60092-504 and the relevant environmental and EMC tests specified in IEC60068/60092 and IEC61000/60533 respectively, to comply with the requirements of the major Classification Societies.

Trip level and current imbalance can be monitored using a high impedance multi-meter on terminals 4,5 and 10. The DC voltage between terminals 5 and 10 show the set trip level, which is adjusted using the sensitivity potentiometer.
