Устройства защитного отключения (диф.защита)
серии SIGMA
Suitable for all fields of application – with certainty: RCCBs
 Sigma RCCBs are protection devices that can protect the human life against dangerous
electrical shocks or can prevent the fires occured from isolation failures by
stating the possible isolation failures before. Sigma RCCBs are produced as 2
and 4 poles according to TS EN 61008-1and CE standards under
ISO9001-2008 quality management systems.
Classification
4 basic factor are to be taken into consideration while choosing SIGMA Residual Current Circuit Breakes
- Level of Residual Current
30 mA RCCB is to be used in order to protect the human life against
direct/indirect touch and 300 mA RCCB is to be used
for fire protection
- Number of Poles
2 poles are used in mono phase network system and 4 poles are used in three phase
network system
- Rated Current
The rated current of Residual Current Circuit Breakers should be the same as or
higher than MCB/MCCB connected before RCCB. The passing
Current inside the RCCB should be lower than the nominal rated current of RCCB.
Selectivity
RCCBs are produced as G (general type) and S (delay type).
