EKL1-63B Type B RCD has novel appearance design, compact structure, good reliability, and high safety. The products comply with IEC61008-1, IEC62423 and other standards, and the product certification is complete; They ensure higher protection levels with maximum operational continuity under all working conditions. For this reason, Type B RCDs are considered universal devices because they provide protection against all the tripping waveforms listed in the Standards EN 62423.Type B RCDs can ensure maximum safety in many applications, such as EV Charging Station, Crane and Elevator, PV and Wind power plants, etc.

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.
