Overview

The Kuangya VKL008 30ma 4 pole rccb detects earth leakage and disconnects the circuit to protect
people and installations from electric shock and fire hazards caused by insulation faults. It is available in
2-pole and 4-pole versions for single-phase and three-phase distribution boards in residential, commercial,
and light-industrial environments.
