Häufig gestellte Fragen
What is the difference between an MCB circuit breaker and an RCCB residual current device?
MCB protects against overload and short circuit, while RCCB monitors for earth leakage current and protects against electric shock and fire. It is best practice to use them together or as a combination RCBO device.
Is SPD surge protection needed in an apartment?
Yes, it is recommended because surges can occur not only from lightning strikes, but also from switching in the network. SPD protects electronics, boilers, air conditioners and office equipment.
How often should protections be tested?
We recommend a monthly test of the RCCB with the Test button and annual preventive maintenance with measurements. When making changes to the installation or adding powerful appliances, it is a good idea to carry out an extraordinary check.
