Overview
The VKL11 is a residual current circuit breaker for residual-current protection in AC 50/60 Hz electrical installations. It disconnects the circuit when earth leakage is detected and is available in Type AC, Type A and high-immunity Type ASi versions. The range covers rated currents from 16 A to 100 A, residual operating currents from 10 mA to 300 mA, and 2P or 4P configurations rated at 240 V AC or 415 V AC. Designed for residential, commercial and industrial distribution systems, it mounts on a 35 mm DIN rail and is intended for use with suitable overload and short-circuit protection.
