Detectable wave form Pulsating direct current sensitive Surge current proof
B class
Tripping is ensured for sinusoidal AC residual currents pulsed DC residual currents, alternating residual sinusoidal currents up to 1000Hz, pulsating direct residual currents and for smooth direct residual currents, whether applied suddenly or increasing slowly.

They react to AC and pulsating DC fault currents which reach 0 or almost 0 within one time period of the main frequency.
