Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
LV429211 is an earth-leakage (residual current) add-on protection module of Vigi MH type, configured for 4-pole mounting on Schneider Electric's ComPact NSX 100/160 circuit-breaker frames. The module monitors leakage currents between 30 mA and 10 A at supply voltages from 200 VAC to 440 VAC, and is designed to supplement NSX breakers with earth-fault sensing capability in industrial and commercial electrical protection schemes. LV429211 is discontinued but remains supported via aftermarket services.
Best Suited For
- Supplementing ComPact NSX 100/160 breakers with earth-fault protection
- 4-pole electrical distribution boards where residual-current monitoring is required
- Applications needing adjustable leakage-current detection from 30 mA to 10 A
- Retrofit upgrades in systems still using ComPact NSX 100/160 breakers
