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 )
