Schneider LV429493 Earth-leakage VigiPacT Module – 4 Poles

The LV429493 Schneider is a VigiPacT earth-leakage alarm module designed to enhance protection in low-voltage power distribution systems. Tailored for use with ComPacT NSX250 circuit breakers, it supports 4-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. Powered by the system voltage—even with only two phases connected—it meets IEC 60947-2 Annex B standards for reliable use in industrial and commercial environments.
