概要

The VKL11F タイプf rccb detects earth leakage including mixed-frequency components that commonly
occur with inverters, VFD-driven motors, and UPS equipment. It disconnects the circuit when residual current
exceeds the set threshold to protect people and installations against electric shock and fire hazards.
Available as 2P (single-phase) and 4P (three-phase).
