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; Hey 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 and Wind power Plantses.
