MN undervoltage release, MV overvoltage trip, MN + MV over or under voltage release 
 Supply over-voltage auxiliary MN + MV 
 I. Scope of this series circuit breaker electrical accessories are designed for my company (DZ47) -63, (DZ47) -100 series circuit breaker auxiliary function supporting design elements, such as in electrical circuits or home, building, can be selected different electrical accessories and (DZ47) -63, (DZ47) -100 series with the circuit breaker in order to achieve circuit breaker undervoltage, overvoltage, undervoltage protection. 
 Supply over-voltage auxiliary MN + MV 
 II. Name of the attachment, use and standard 
 (DZ47) -63, (DZ47) -100 series circuit breaker attachment name, purpose and meet the criteria in Table 1. 
 Code uses the standard attachment name 
 Undervoltage release (MN) when the power supply voltage drop in (0.35 ~ 0.75) Ue between, the circuit-breaker, to achieve the line under-voltage protection. IEC60947-2: 1999, GB14048.2-2001 
 Over-voltage trip (MV) when the supply voltage up to 270 ± 5% when the circuit-breaker, to achieve the over-voltage protection circuit. IEC60947-2: 1999, GB14048.2-2001 
 However, the undervoltage release (MN + MV) when the rated voltage of 220V to 270 ± 5% increase or decrease in the 170 ± 7V when the circuit-breaker, to achieve circuit protection. IEC60947-2: 1999, GB14048.2-2001 
 Supply over-voltage auxiliary MN + MV 
 Third, the main technical parameters of overvoltage, undervoltage, over voltage trip, undervoltage protection technical parameters (see Table 2) 
 Rated operating voltage Ue attachment name voltage wiring diagram action 
 Overvoltage trip AC: Un = 230V (overvoltage) 270 V ± 5% 

 Undervoltage release AC: Un = 230V (voltage) 170 V ± 5% 
 However, the undervoltage release AC: Un = 230V (over, under-voltage) over-voltage: 2705 ± 5% V under-voltage: 170 ± 7V 
 Installation of all electrical accessories are to add a side of the circuit breaker 
 Note: the attachment in the circuit breaker can be left more than stitching, stitching the right side of the circuit breaker can only be a piece of accessories and installation conditions of ambient temperature: -5 ℃ ~ +40 ℃; Altitude: not exceed 2000m; environmental conditions : There should be no danger of explosion of media, nor will corrode and damage the insulation and conductive dust, harmful gases; installation conditions: The 35mm standard rail installation.
