VKL11 (B\/B+) is a b type rccb<\/strong> designed to disconnect the circuit when residual current exceeds
\nthe threshold, helping prevent electric shock and fire hazards due to insulation faults. The Type B\/B+ variants
\nare suitable for leakage containing smooth DC and higher-frequency components often present with frequency
\nconverters, inverters, PV\/EV equipment, and VFD-driven motors. Pole options include 2P for single-phase and
\n4P for three-phase systems.<\/p>\n
