| |
|
2. Applicable standards |
| |
International standard:
IEC 61008-1 residual current operated without integral over current
Protection of household and similar uses (RCCB) |
| |
| |
|
3. Normal usage and mounting conditions: |
| |
|
|
a) Ambient temperature: the breaker can work under ambient air temperature -25℃ ~+40℃;
b)Altitude: the breaker can work under altitude not exceed 2000m;
c)Class of pollution: the class of pollution is class 2;
d)Installation type: the installation type is Ⅲ;
e) Mounting position: the breaker can be mounted in rail, or horizontally, vertically. it will not decrease their electric features:
f)Environmental protection: Environmental factors are adequately considered in the design of circuit breaker, with many recoverable and degradable materials.
g)Power source in-line: the in-line can be connected from different directions, which will not affect its electric features. |
