whether suddenly applied or slowly rising.
4. Tripping sensitivity data
RCD with a rated residual current of maximum 30 mA are used for personnel,material and fire protection, as well as for protection
against direct contact.
RCD with a rated residual current of maximum 300 mA are used as preventative fire protection in case of insulation faults.
RCD with a rated residual current of 100 mA co-ordinated with the earth system according to the formula IΔn<50/R, to provide
protection again indirect contacts.
