Tripping Current Range

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 current which reach 0 or almost
0 within one time period of the
mains frequency.
