Product main features:
Overvoltage and undervoltage tripping device MV+MN, DZ47 220V, over and under voltage tripping deviceMV+MN is specifically for DZ47 air switch research and development of a DZ47 accessory products, mainly forfamily use, when the family of voltage instability to protection, household electrical equipment such as: TV, icebox, air conditioning, electric rice cooker, pressure cooker, washing machine and other equipment, when voltagesuddenly increased or reduced when suddenly, a lot of home appliances products may be due to voltageinstability and lead to damage or the burning of household appliances, when you install the overvoltage undervoltage tripping device can give your household appliances play a very good protection of our company production, the specific parameters are as follows.
Name, DZ47 series circuit breaker accessories use and meet the standards see table 1.
Standard consistent with the use of way attachment name generation No.
Undervoltage tripper MN when power supply voltage drops in the 170V + 5%, so that the circuit breaker tripping,owe to achieve line voltage protection. IEC60947-2:1999, GB14048.2-2001
Overvoltage tripping device is MV when the power supply voltage up to 270V + 5%, so that the circuit breakertripping, over voltage protection circuit implementation of the. IEC60947-2:1999, GB14048.2-2001
Overvoltage, undervoltage tripping device MV+MN when 220V rated supply voltage up to 270V + 5% ordecreased in the 170V + 5%, so that the circuit breaker tripping, the realization of line protection. IEC60947-2:1999, GB14048.2-2001
Overvoltage and undervoltage tripping device MV+MN, DZ47 220V, belt line, main technical parameters ofovervoltage, undervoltage, overvoltage and undervoltage tripping device, undervoltage protection technology parameter (see Table 2)
Name of the attachment of rated voltage Ue operation voltage wiring diagram
Overvoltage tripping device AC:Un=220V (overvoltage) 370 V + 5%
Undervoltage tripping device AC:Un=380V (undervoltage) 170 V + 5%
Overvoltage, undervoltage tripping device AC:Un=220V (too, undervoltage overvoltage): 370V + 5%
Under pressure: 170 V + 5%
Simple installation
When you purchase our company DZ47 over-voltage protection device MV+MN products, you can directlyinstalled in the general switch right, to be below the two leads are respectively connected to the outlet so that the completion of.
