개요

VKL11 (B/B+) is a b type rccb designed to disconnect the circuit when residual current exceeds
the threshold, helping prevent electric shock and fire hazards due to insulation faults. The Type B/B+ variants
are suitable for leakage containing smooth DC and higher-frequency components often present with frequency
converters, inverters, PV/EV equipment, and VFD-driven motors. Pole options include 2P for single-phase and
4P for three-phase systems.
