The Type B System consists of a CT and a PCBA. This system is designed to be integrated into any standard 2 pole or 4 pole VI RCCB to produce a 2 pole or 4 pole 30mA Type B RCCB. A standard Type A RCCB can therefore be easily upgraded to a full B Type RCCB by integration of the component system. Residual current rating of 300mA is also available.
Complies with IEC62423 (EN62423)
Suitable for integration into most 2 pole or 4 pole RCCB products
Powered from any two poles
System provides 30 mA AC and 60 mA DC residual current detection
A standard Type A RCCB can therefore be easily upgraded to a full B Type RCCB by integration of the component system.
