Tổng quan
The VKL11B Type B and VKL11B+ Type B+ residual current circuit breakers provide residual-current protection in AC 50/60 Hz installations that may generate alternating, pulsating DC or smooth DC residual currents. Type B detects frequencies up to 1 kHz, while Type B+ extends detection up to 20 kHz. The range includes 16 A to 100 A ratings, 2P and 4P configurations, and instantaneous, K short-time-delayed or T selective versions. It is intended for installations using frequency converters, photovoltaic systems, UPS systems and other electronically controlled equipment. Suitable overload and short-circuit protection must be provided separately.
