Legrand 2P 63A 30mA RCCB (DX3) – [Residential]

The Legrand DX3 RCCB DP 63A 2P AC is a 240V residual current circuit breaker designed to provide critical earth leakage protection for residential systems. This 2-pole unit monitors a 63A current flow and disconnects the circuit immediately upon detecting a 30mA imbalance. It occupies exactly 2 modules (36mm) on a standard 35mm DIN rail for space-efficient installation.

Quick Answer

Absolutely, you should buy the Legrand DX3 2P 63A 30mA RCCB if upgrading or installing a new residential electrical system. Its critical 30mA sensitivity provides instant earth leakage protection, preventing serious shock hazards and ensuring human safety. With a robust 10kA breaking capacity, this device guarantees reliable performance even during significant fault currents, making it a cornerstone for comprehensive home electrical security in India.

✓Protects residents from direct contact shocks — 30mA sensitivity trips the circuit instantaneously.
✓10kA breaking capacity — ensures the device remains functional even after handling significant fault currents.
✓High durability in tropical climates — operating temperature range from -5°C to +55°C ensures stability.
✓630A making and breaking capacity — provides robust handling of temporary current surges during operation.
✓Flame retardant housing for peace of mind — UL94 V0 rating and 850°C glow wire test compliance.
✓Halogen-free and RoHS compliant — ensures no toxic fumes are released during high-heat electrical events.

For Indian homeowners and residential electricians, this Legrand 2P 63A 30mA RCCB is essential, offering critical earth leakage protection against fatal shocks. It's a key safety upgrade. Avoid if your project is commercial/industrial, requiring different specifications.

Engineering Analysis
A 30mA sensitivity is vital for residential safety because it trips the circuit before current levels reach the threshold of human heart fibrillation. The 10kA breaking capacity ensures the device maintains structural integrity during high-magnitude faults at the incomer. Switched neutral protection in this 2P configuration ensures the entire circuit is isolated during a trip, eliminating any risk of back-fed neutral voltages.
