What is the difference between type A & AC class RCCB ?
In Class A (Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed ,DC residual currents, whether they are quickly applied or slowly increased.
Application: loads with electronics, rectifiers, and instruments.)
