VigiPacT Residual current monitoring relay

Vigipact relays detect insulation faults by continuously monitoring earth leakage current. Then they offer 2 options:

• Protection: when leakage current reaches the set threshold, they trip the circuit-breaker upstream, by activating its shunt trip auxiliary.
• Monitoring and alarming, by LED, bar graph, or digital touchscreen on front, and by a dry contact output. Multi-line versions are capable of monitoring up to 12 lines with one device, connected to 12 current sensors.
