1.Ambient Air Temperature: -5oc ~ +40oc, and Average Temperature in 24H is Below +35oc.
2.ALTITUDE: The Altitude of the Installation site is not more than 2000m.
, And Consider The Temperature Changes in Product on the Surface of the Gel.
4. Pollution Degree: 3.
Selection of Instructures
Account to the pain, it classifies four types:
Type A: n-POLE Without Over-Current Release Components, and N-POLE HAS Been Connected All Along, and Does Not Act with OTHER Three Poles on or OFF;
B-Type: N-POLE Without Over-Current Release Components, and N-POLE COULD ACT with Other Three Poles (N-POLE TURN-ON Prior To Turn-OFF);
Type C: N-POLE FIXED with Over-Current Release Components, and N-POLE COULD ACT WITH OTHER Three Poles (N-POLE TURN-On Prior to Turn-OFF);
Classification of the Rated Current of Over-Current Release:
DAM2-63 MCCB has nine: 6,10,16,20,25,32,40,50,63 A;
DAM2-100 MCCB has nine: 16,20,25,32,40,50,63,80,100 A;
DAM2-250 MCCB has seven: 100,125,140,160,180,225, 250A;
DAM2-400 MCCB has Five: 225,250,315,350,400 A;
DAM2-630 MCCB Has Three: 400,500,630 A;
DAM2-800 MCCB has Three: 630,700,800A;
DAM2-1250 MCCB has Three: 800,1000,1250A.
Remark: 6a only has electromagnetic (Instantaneous) Type, is not recomdynded specifications.
According to the Willing Method: Wiring in Front of Board, Wiring on Back of Board, Insertion Type of the Board.
According To Over-Current Release Pattern: Thermodynamic-Electromagnetic (Double) Type, Electromagnetic (Instantaneous) Type.
According to the outfit, it has two types: with or without outfit.
Account to the breaking capacity: L-Standard Breaking Type; M-Second High Breaking Type; H-High Breaking Type

Release to prevent the circuit breaker is closed; when the support is higher than 85% of the rate of the Under-Voltage
Release, The Under-Voltage Release Ensures that the Circuit Breaker is Closed. The UnderVoltage Releases Are Rated at AC50Hz, 230V, 230V
400v.
SPECIAL NOTE: The Circuit Breaker with UnderVoltage Release, only in the under-voltage with rate, Which Can Open and Close
normally.
