Overview

The Kuangya VFL008 circuit breaker rccb type disconnects the circuit when residual current exceeds the
preset threshold, preventing electric shock and fire hazards due to insulation faults. Available in both 2-pole and
4-pole versions, this circuit breaker rccb type suits single-phase and three-phase distribution boards in homes,
offices, and light-industrial facilities.
