Legrand 2P 25A 30mA RCCB (DX3) – Residential

The Legrand DX3 RCCB FP 25A 30mA is a 2-pole residual current circuit breaker designed specifically for residential final circuit protection.

Quick Answer

The Legrand DX3 2P 25A 30mA RCCB is a vital acquisition for residential safety. It delivers 30mA human life protection, instantly cutting power during earth leakages to prevent severe electrical shocks. Crucially, its 10kA breaking capacity handles high-energy faults in Indian urban grids, offering robust protection for both occupants and appliances when paired with an MCB.

✓Prevents accidental electrocution — 30mA residual current sensitivity trips the circuit instantly.
✓10kA breaking capacity — ensures the device handles high fault currents safely in residential environments.
✓Protects sensitive electronics from surges — 4kV impulse withstand voltage shields your household appliances.
✓Compact 2-module design — 36mm width fits standard DIN rail installations without crowding the panel.
✓Long-term operational reliability — 10,000 mechanical cycles ensure years of consistent safety performance.
✓850°C glow wire test rating — high-grade flammability protection prevents the device itself from becoming a fire hazard.

This Legrand DX3 RCCB is crucial for Indian residential users needing 30mA human safety and 230V circuit fault protection. Buy it to guard against shocks. Avoid if requiring industrial use or if a functional 30mA RCCB is present.

Product Overview
The Legrand DX3 RCCB FP 25A 30mA is a 2-pole residual current circuit breaker designed specifically for residential final circuit protection. This device monitors current balance and provides essential earth leakage protection by disconnecting the 230V supply when a fault is detected. Rated at 25A, it functions as a critical safety component when paired with a backup MCB in standard household distribution boards.

Engineering Analysis
A 30mA sensitivity rating is the global standard for human life protection, as it interrupts current before it can cause cardiac arrest. The 10kA breaking capacity ensures the device can safely handle high-energy faults common in urban Indian grids without catastrophic failure. With a switched neutral in its 2P configuration, it provides complete isolation of the circuit during a trip event, ensuring no residual voltage remains.
