Coupling capacitors types CCA (standard capacitance) and CCB (extra high capacitance) are intended for power line carrier applications. The insulator and capacitor design are identical to capacitor voltage dividers type CSA and CSB, but without an intermediate voltage terminal.
A line trap can in most cases be mounted directly on top of the coupling capacitor. Primary terminal according to ABB standard, as well as insulators for the pedestrial mounting are part of the delivery.
