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
You should invest in the Legrand DX3 2P 25A 30mA RCCB if you need life-saving earth leakage protection for household circuits. Its 10kA breaking capacity is built for the voltage fluctuations of Indian urban grids. Unlike basic breakers, this DX3 model ensures a switched neutral for complete isolation during a trip.
✓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.
Opt for this DX3 RCCB to protect human life in damp areas like kitchens or bathrooms, but avoid it for heavy industrial loads exceeding 25A. It’s the gold standard for residential safety where 30mA sensitivity is non-negotiable.
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.
