Schneider LV429488 Earth-leakage VigiPacT Module – 3 Poles

The LV429488 Schneider is a VigiPacT earth-leakage alarm module designed to enhance protection in low-voltage power distribution systems. Tailored for use with ComPacT NSX100 and NSX160 circuit breakers, it supports 3-pole configurations and operates at 200–440 VAC, 50/60 Hz.

It offers adjustable sensitivity from 30 mA to 30 A, enabling early fault detection with alarm functionality without tripping the breaker. Self-powered by the system voltage—even when supplied by only two phases—it complies with IEC 60947-2 Annex B standards, ensuring reliable performance in industrial and commercial environments.
