Install the Unit/Extension type in one body
 - The display part may be separated from the body You can check the values and the causes of the fault without opening the distribution ● panel door
 
Standard
- IEC60947-1, IEC60947-4-1, IEC60947-5-1, UL508, KSC4504


Certification & approval:
- CE, UL, cUL, Lloyd register, Korea register, KS, ISO 14001, ISO 9001(Including proceedings)




Display the causes of the fault and the values
- Prompt A/S by looking the LED panel which displays the causes of the fault and the values
 
3phase digital ampere-meter function (Digital ampere-meter)
- Additional ampere-meter is not needed

Motor load rate(%)
 - Easy to check the motor load condition
Selectable either the inverse time or definite time characteristics

Applicable to inverter control circuit
 - LS DMPR has high performance under the harmonic noise and can be used in the Inverter control circuit (20~200Hz)
 
Elegant design
- High class product image by the elegant design
 
 
Characteristics

Protect function
 
Over current Depend on setting time Selectable the inverse/definite
Phase loss Within 3seconds Over 70% of the rate of unbalance
Phase unbalance Within 5seconds Over 50% of the rate of unbalance
Phase reverse Within 0.1seconds Function enable
Stall Within 5seconds Over 180% of the setting current
Lock Within 0.5seconds Setting 200~900% of rated current
Under current Within 3seconds Setting 30~70% of rated current
Ground fault Note) Selectable 0.05~1.0seconds Grounded current setting by dip s/w (100~2500mA)

Note) Lock protection is operated after setting D-time in case of definite time type
