Schneider LV429491 Earth-leakage VigiPacT Module

The LV429491 Schneider is a VigiPacT earth-leakage add-on protection module designed for enhanced safety in low-voltage power distribution systems. Specifically engineered for integration with ComPacT NSX100/160 circuit breakers, this module supports 4-pole configurations and operates within a voltage range of 440–550 VAC at 50/60 Hz.

It offers adjustable earth-leakage sensitivity from 30 mA to 30 A, providing early fault detection with alarm functionality without tripping the breaker. This feature enhances system safety by allowing timely maintenance interventions. The module is compliant with IEC 60947-2 Annex B standards, ensuring reliable performance in industrial and commercial environments.
