Legrand 4P 25A 100mA RCCB (DX3) – Residential

The Legrand DX3 RCCB FP 25A 100mA is a four-pole residual current circuit breaker designed specifically for residential main incomer applications. It provides dedicated earth leakage protection by monitoring current balance across all four poles to detect faults as low as 100mA.

Quick Answer

For Indian homeowners with a 4-pole main supply, the Legrand DX3 4P 25A 100mA RCCB is ideal. Its 100mA sensitivity specifically addresses fire protection in residential units, cleverly balancing safety against nuisance tripping often faced with more sensitive devices. With a 10kA breaking capacity, this robust circuit breaker ensures critical earth fault protection and system integrity, making it a reliable choice for main incomer applications.

✓Protects your property from electrical fires by sensing leaks above 100mA sensitivity.
✓Rapid fault interruption with instantaneous tripping occurring in less than 300ms at 1x Idn.
✓Operates reliably in diverse Indian climates thanks to a temperature range of -5°C to +55°C.
✓High durability for long-term safety with 10,000 mechanical and 4,000 electrical endurance cycles.
✓Provides a clear visual status of your electrical health through the integrated trip indicator.
✓Robust construction confirmed by an 850°C glow wire test and UL94 V 0 flammability rating.

This Legrand RCCB is perfectly suited for residential installations needing 4-pole main incomer protection against fire, where a 100mA sensitivity prevents nuisance trips. Avoid if direct human shock protection (requiring 30mA) is your primary concern, or if your setup is single-phase and doesn't require a 4-pole device.

Engineering Analysis
A 100mA sensitivity is the standard for fire protection in residential units where a 30mA device might cause nuisance tripping. The 10kA breaking capacity ensures the device remains intact during high-magnitude short circuits, while the 4P configuration allows for complete isolation including the switched neutral.
