All protection elements installed upstream must have the same or higher rating than those installed downstream, never lower, in order to guarantee the correct operation of the selective classification process. Therefore, if Type B is the maximum protection level of an element, a type A or AC unit cannot be installed downstream.
CIRCUTOR's range of Type B earth leakage protection units covers all the protection levels in your installation.
