A Q1 ： What's the differences of Terminal Block with Connector?
- Terminal Block ：Used for wire connection forever ,usually be installed in Din rail /panel.
- Connector ：Used for devices /equipment interface plug-and -play, for example,USB,Aviation plug
- Key difference ：Terminal Block is emphasis realiable and firm,then, connector is stresses on plug -play 
 
 
  Q2 ： How to calculate the actual current capacity?
 
Actaul current = rated current × temperature coeficient × contact number
 
- temperature coeficient ： 40 ℃ → ratio  0.8
-  contact number：3 wires in parallel  →ratio   0.7
- example ： 25A terminal block  → actual use ≤  25 × 0.8 × 0.7=14A
 
 
  Q3 ： Why does strand wire need to use cold press connector ？
-  To avoid filoselle：ensure all wires be in contact area.
- Reduse resistance ：avoid connection superheating in part
- Standard request ： IEC 60947-7-1compulsory stipulate ＞ 1.5mm ⊃2; obligate to pressure welding.
 
 
Q4 ： Common causes of terminal block heating？
1. poor contact （ 45% ）→ clean the contact， Re-tighten.
2. Overload （ 30% ）→ check the actual current， change to be large size.

 
Q5 ： Which certificates need  approved  exporting to Europe and America？
- North american Market ： UL 1059 + CSA 22.2 No.0.4
- Europe Market ： CE + IEC 60947-7-1 + RoHS
