temperature:-40ºC~+80ºC Heat and humidity resistance:The relative
air humidity ≤95% at the temperature of +55ºC Altitude:≤2000m, if
you want to apply it more than 2000m, you must refer to Miniature
Circuit Breaker's reduced capacity table. Also you can refer to
GB/T20645 the technological requirement of the low-voltage
electrical equipment when it is used on high altitude. Pollution
degree: 3Free from obvious vibration or shockInstallation method
Modular construction,can be installed in TH35mm * 7.5 standard
guide rail. 9.Connect line requirements The wire capacity:
1mm²~25mm²conducting wire Terminal screw: M5; Maximum ultimate
torque : 2.0N.m10.Packaging and storage Quantity(1P
product:12PCS/box,1PN/2P product:6PCS/box,3P product:4
PCS/box,3PN/4P product: 3PCS/box),Packing boxes of products should
be stored in the air circulation and relative humidity is not more
than 80% and the temperature is not higher than + 80 ºC,Not less
than - 40 ºC in the air around without acid, alkali or other
corrosive gases stored in the warehouse. In the above conditions,
the storage period since the production date not more than three
years.11.Accessory list and installation OF1 Auxiliary Contact Be
installed to the left side of NDB1-63 to indicate the t ripping
status of the breaker. SD1 Alarm Contact Be installed to the left
side of NDB1-63 to indicate the fault tripping status of the
breaker. MX+OF1 Shunt Release Be installed to the left side of
NDB1-63,remotely controls the breaker opening and indicates the
breaker tripping statusGQ1A Over&Under Voltage Tripping Device
Be installed to the left side of NDB1-63,used for circuit of work
voltage less than AV230V,which has defensive function such as
over-voltage protection(G1A), 3P 3PN, 4P File No.:NDT2930143
Version:3 Page 8 of 8 low-voltage
protection(Q1A),over&low-voltage protection(GQ1A),at the same
time,no-tripping when power down; FF1 Double Auxiliary Contact Be
installed to the left side of NDB1-63 to indicate the tripping
status of the breaker FS1 Auxiliary and Alarm Contact Be installed
to the left side of NDB1-63 to indicate the fault tripping status
of the breaker. NDB1LE-63 residual current operated protective
module Be installed on the right of NDB1-63 miniature circuit
breaker, is applied to protect direct or indirect earth leakage
faults. Notices 1.The user should responsible for the quality
problem caused by taking the products apart or adjust the tripping
parameters without permission.2.Touch the uninsulated bare part is
not allowed when breaker is energized state. 3.Make sure reliable
connection to prevent the abnormal heating of terminals. That can
cause fault operation of breakers or terminal damage.4.Please
remove the cover before installation, details please refer to
