RCCB Earth leakage protection 4P 63A 500mA B-class-SI, Super Immun AC/DC for installations with 3Phase speed drive and inverter due to DC current

Acti9 iID B-SI type fault RCCB provides:
- protection in case of a continuous earth fault current on the network
generated by:
- div controllers and frequency converters,
battery chargers and converters used in ex PV photovoltaic applications
as well as back-up power supplies.
- They include protection from earth fault currents:
- sinusoidal AC residual currents (AC type),
- Pulse DC residual currents (A type),
- Multi frequency residual current (F type).
- It is possible to use Acti9 iID B-SI type AC power switch
mandatory, according to applicable standards in the country.
- For applications using 3-phase drives, such as:
- cranes,
- hoisting and lift,
- HVAC,
- pumping system.
In the above installations, B type AC / DC is required.
