Product Overview
Vigi Earth Leakage Protection Module
The Vigi add-on module provides enhanced earth leakage protection for compatible circuit breakers without modifying their core electrical or installation characteristics. Designed for seamless integration, these modules are self-powered by the distribution-system voltage, ensuring continuous operation even when supplied by only two phases. The system supports remote signaling of earth fault tripping via auxiliary contacts and offers adjustable sensitivity and time-delay settings for selective protection.
