MN undervoltage tripping device, MV overvoltage tripping device, MN+MV undervoltage tripper
One, applicable scope
The series circuit breaker electrical accessories are specially designed for the ( DZ47 ) -63, ( DZ47 ) -100 series circuit breaker supporting design of auxiliary function element, in the electrical circuit or home furnishing, buildings, can be chosen according to the different needs of the electrical accessories and ( DZ47 ) -63, ( DZ47 ) -100 series circuit breaker with, to circuit breaker circuit, overvoltage, undervoltage overvoltage and undervoltage protection function.
In two, the name of the attachment, use and standard of
( DZ47 ) -63, ( DZ47 ) -100 series circuit breaker accessories name, purpose and standard of table 1.
Attachment name code uses standard
Undervoltage tripping device ( MN ) when the supply voltage drops in ( 0.35 ~ 0.75 ) Ue between, make the circuit breaker tripping, realizes line undervoltage protection. IEC60947-2:1999, GB14048.2-2001
Overvoltage tripping device ( MV ) when the supply voltage is increased to 270±5%, make the circuit breaker tripping, realize line overvoltage protection. IEC60947-2:1999, GB14048.2-2001
Too, undervoltage tripping device ( MN+MV ) when 220V rated supply voltage rises to 270± 5% or 170±7V, drop in, the circuit breaker tripping, realization of line protection. IEC60947-2:1999, GB14048.2-2001
In three, the main technical parameters of overvoltage, under voltage, overvoltage and undervoltage tripper, under-voltage protection device technical parameters ( see Table 2 )
Attachment of rated voltage Ue operation voltage
Overvoltage tripping device AC:Un=230V ( OV) 270 V± 5%
Undervoltage tripping device AC:Un=230V ( 170 V ± 5% under-voltage )
Too, undervoltage tripping device AC:Un=230V (, undervoltage overvoltage ): 2705 ± 5%V under pressure: 170 ± 7V
Install all electrical accessories are coupled on the side of circuit breaker
Note: in circuit breaker left splicing attachment can be more than one, in the right of breaker splicing attachment of only 1 and the mounting conditions of the environment temperature: -5 ℃~ +40 ℃; altitude: not more than 2000m; environmental conditions : there should be no cause explosive medium, nor can corrupt and broken insulation harmful gas and electric dust; installation conditions: using the standard 35mm card track installation.
